Hash tables 75 Your buddy Maggie can give you the price in O 1 time for any item, no matter how big the book is. What a wonderful person! You could implement this book as an array. Each item in the array is really two items: one is the name of a kind of produce, and the other is the price. If you sort this array by name, you can run binary search on it to ind the price of an item. So you can ind items in O log n time. But you want to ind items in O 1 time. In the best case, every diferent word should map to a diferent number.
So a hash function maps strings to numbers. What is that good for? Keep going, and eventually the whole array will be full of prices. It tells you that the price is stored at index 4. And sure enough, there it is. So you can use it the irst time to ind where to store the price of an avocado, and then you can use it to ind where you stored that price. Everything maps to a diferent slot in the array where you can store its price. Put a hash function and an array together, and you get a data structure called a hash table.
Arrays and lists map straight to memory, but hash tables are smarter. And hash tables are fast! Remember our discussion of arrays and linked lists back in chapter 2? You can get an item from an array instantly. Any good language will have an implementation for hash tables.
In the book hash, the names of produce are the keys, and their prices are the values. A hash table maps keys to values. Which of these hash functions are consistent? Using hash tables for lookups Your phone has a handy phonebook built in. Each name has a phone number associated with it. Hash tables make it easy to model a relationship from one item to another. Hash tables are used for lookups on a much larger scale. Your computer has to translate adit. Use cases 81 For any website you go to, the address has to be translated to an IP address.
Wow, mapping a web address to an IP address? Sounds like a perfect use case for hash tables! Hash tables are one way to provide this functionality. Naturally, every person can vote just once. When someone comes in to vote, you ask for their full name. If their name is on the list, this person has already voted—kick them out!
Otherwise, you add their name to the list and let them vote. Now suppose a lot of people have come in to vote, and the list of people who have voted is really long.
Otherwise, it returns None. You can use this to check if someone has already voted! Checking for duplicates is very fast with a hash table. Using hash tables as a cache One inal use case: caching. If you work on a website, you may have heard of caching before as a good thing to do.
Suppose you visit facebook. You get a web page. It takes a couple of seconds to collect all that activity and shows it to you. Is there a way to make Facebook faster and have its servers do less work at the same time? Suppose you have a niece who keeps asking you about planets. Each time you go to facebook. Everyone sees the same login page. Instead, it memorizes what the home page looks like and sends it to you. You can answer instantly. Caching is a common way to make things faster.
All big websites use caching. And that data is cached in a hash! So it needs a mapping from page URL to page data. When you visit a page on Facebook, it irst checks whether the page is stored in the hash.
Before you return the data, though, you save it in the cache. But you still care about performance! To understand the performance of hash tables, you irst need to understand what collisions are. I told you that a hash function always maps diferent keys to diferent slots in the array. Suppose your array contains 26 slots. And your hash function is really simple: it assigns a spot in the array alphabetically. Collisions 87 Maybe you can already see the problem.
You want to put the price of apples in your hash. You get assigned the irst slot. You get assigned the second slot. Everything is going so well! But now you want to put the price of avocados in your hash. You get assigned the irst slot again. Oh no! Apples have that slot already! What to do? Collisions are bad, and you need to work around them. So you start a linked list at that slot. If the linked list is small, no big deal—you have to search through three or four elements.
But suppose you work at a grocery store where you only sell produce that starts with the letter A. Hey, wait a minute! And that slot has a giant linked list! Every single element in this hash table is in the linked list. Your hash function mapped all the keys to a single slot. Ideally, your hash function would map keys evenly all over the hash. Hash functions are important. A good hash function will give you very few collisions.
So how do you pick a good hash function? Performance You started this chapter at the grocery store. You wanted to build something that would give you the prices for produce instantly.
Well, hash tables are really fast. In the average case, hash tables take O 1 for everything. O 1 is called constant time. It means the time taken will stay the same, regardless of how big the hash table is.
For example, you know that simple search takes linear time. Binary search is faster—it takes log time: Looking something up in a hash table takes constant time. Getting an item out of an array takes constant time. In the average case, hash tables are really fast. Look at the average case for hash tables.
Hash tables are as fast as arrays at searching getting a value at an index. But in the worst case, hash tables are slow at all of those. And to do that, you need to avoid collisions. Whatever programming language you use will have an implementation of hash tables built in. You can use the built-in hash table and assume it will have good performance. The next section gives you a peek under the hood. Load factor he load factor of a hash table is easy to calculate. Hash tables use an array for storage, so you count the number of occupied slots in an array.
Load factor measures how many empty slots remain in your hash table. Suppose you need to store the price of produce items in your hash table, and your hash table has slots. In the best case, each item will get its own slot. What if your hash table has only 50 slots?
Having a load factor greater than 1 means you have more items than slots in your array. Once the load factor starts to grow, you need to add more slots to your hash table. For example, suppose you have this hash table that is getting pretty full. You need to resize this hash table. Much better! A good rule of thumb is, resize when your load factor is greater than 0. But averaged out, hash tables take O 1 even with resizing.
A good hash function A good hash function distributes values in the array evenly. A bad hash function groups values together and produces a lot of collisions. What is a good hash function? You could use that as your hash function. Suppose you have these four hash functions that work with strings: a. Use the length of the string as the index. Use the irst character of the string as the index.
So, all strings starting with a are hashed together, and so on. For a string, the hash function is the sum of all the characters modulo the size of the hash.
For each of these examples, which hash functions would provide a good distribution? Assume a hash table size of 10 slots. You need a hash function that minimizes collisions. Breadth-irst search allows you to ind the shortest distance between two things.
But shortest distance can mean a lot of things! You want to get there by bus, with the minimum number of transfers. Here are your options. Well, can you get there in one step? Here are all the places you can get to in one step. Can you get there in two steps? What about three steps? Now the Golden Gate Bridge shows up. So it takes three steps to get from Twin Peaks to the bridge using this route. It could be the smallest number of moves to checkmate in a game of chess. Model the problem as a graph.
Solve the problem using breadth-irst search. What is a graph? A graph models a set of connections. For example, suppose you and your friends are playing poker, and you want to model who owes whom money. Graph of people who owe other people poker money Alex owes Rama money, Tom owes Adit money, and so on. Each graph is made up of nodes and edges. Graphs are made up of nodes and edges. A node can be directly connected to many other nodes.
Graphs are a way to model how diferent things are connected to one another. Breadth-irst search We looked at a search algorithm in chapter 1: binary search. Breadth- irst search is a diferent kind of search algorithm: one that runs on graphs. Are you connected to a mango seller on Facebook? Well, you can search through your friends. First, make a list of friends to search. Breadth-irst search Now, go to each person in the list and check whether that person sells mangoes.
Suppose none of your friends are mango sellers. Each time you search for someone from the list, add all of their friends to the list. Remember, the goal is to ind one mango seller in your network. Is there a mango seller in your network?
Who is the closest mango seller? Can you ind the closest mango seller? For example, your friends are irst-degree connections, and their friends are second-degree connections.
Well, breadth-irst search already does this! Pop quiz: who will be checked irst, Claire or Anuj? Answer: Claire is a irst- degree connection, and Anuj is a second-degree connection. So Claire will be checked before Anuj. Another way to see this is, irst-degree connections are added to the search list before second-degree connections.
You just go down the list and check people to see whether each one is a mango seller. Breadth-irst search not only inds a path from A to B, it also inds the shortest path. Well, Anuj is a second-degree contact, and Claire is a irst-degree contact. Queues A queue works exactly like it does in real life. Suppose you and your friend are queueing up at the bus stop. A queue works the same way.
Queues are similar to stacks. Instead, there are two only operations, enqueue and dequeue. You can use this for your search list! People who are added to the list irst will be dequeued and searched irst. Implementing the graph Implementing the graph First, you need to implement the graph in code. A graph consists of several nodes. And each node is connected to neighboring nodes.
Luckily, you know a data structure that lets you express relationships: a hash table! Remember, a hash table allows you to map a key to a value. In this case, you want to map a node to all of its neighbors. A graph is just a bunch of nodes and edges, so this is all you need to have a graph in Python. What about a bigger graph, like this one? For example, both of these graphs are equal. Note When updating queues, I use the terms enqueue and dequeue.
Push is almost always the same thing as enqueue, and pop is almost always the same thing as dequeue. Make a queue to start. Implementing the algorithm And so on. Alice and Bob share a friend: Peggy. So once you search a person, you should mark that person as searched and not search them again. Suppose the mango seller graph looked like this. To start, the search queue contains all of your neighbors. Now you check Peggy. And so on. So the running time is at least O number of edges.
You also keep a queue of every person to search. Adding one person to the queue takes constant time: O 1. Doing this for every person will take O number of people total.
From this graph, you can make a list of the order in which I need to do my morning routine: 1. Wake up. Brush teeth. Eat breakfast. Make a valid list for this graph.
You could say that this list is sorted, in a way. If task A depends on task B, task A shows up later in the list. You could topologically sort the graph and get a list of tasks to do, in order. Implementing the algorithm Suppose you have a family tree. A tree is a special type of graph, where no edges ever point back.
Otherwise, you might end up in an ininite loop. But suppose you add travel times to those segments. You used breadth-irst search in the last chapter.
Breadth-irst search will ind you the path with the fewest segments the irst graph shown here. What if you want the fastest path instead the second graph? Each segment has a travel time in minutes. But that path takes 7 minutes. Update the costs of the neighbors of this node.
Calculate the inal path. Step 1: Find the cheapest node. How long does it take to get to each node? It takes 6 minutes to get to node A and 2 minutes to get to node B. Hey, you just found a shorter path to node A! It used to take 6 minutes to get to node A. When you ind a shorter path for a neighbor of B, update its cost. Step 1 again: Find the node that takes the least amount of time to get to.
Woo, it takes 6 minutes to get to the inish now! Find the cheapest node. If so, update their costs. Coming up in the next section! But irst let me clarify some terminology.
A graph with weights is called a weighted graph. A graph without weights is called an unweighted graph. Terminology To calculate the shortest path in an unweighted graph, use breadth-irst search. Graphs can also have cycles.
A cycle looks like this. It means you can start at a node, travel around, and end up at the same node. Would it make sense to follow the cycle? Well, you can use the path that avoids the cycle. Or you can follow the cycle. You could even follow the cycle twice if you wanted. So following the cycle will never give you the shortest path. Finally, remember our conversation about directed versus undirected graphs from chapter 6? An undirected graph means that both nodes point to each other. With an undirected graph, each edge adds another cycle.
Rama is trying to trade a music book for a piano. With a little bit of money, Rama can trade his way from a piano book to a real piano. Now he just needs to igure out how to spend the least amount of money to make those trades. In this graph, the nodes are all the items Rama can trade for. How is Rama going to igure out the path from the book to the piano where he spends the least dough?
Before you start, you need some setup. Make a table of the cost for each node. To calculate the inal path, you also need a parent column on this table. Is there a cheaper way to trade for the poster? Answer: No. If you take the path toward the school, that takes 2 minutes.
If you take the path toward the park, that takes 6 minutes. Is there any way you can take the path toward the park, and end up at the school, in less than 2 minutes?
On the other hand, can you ind a faster path to the park? Back to the music example. Step 2: Figure out how long it takes to get to its neighbors the cost.
You have prices for the bass guitar and the drum set in the table. Step 2 again: Update the values of all of its neighbors. Hey, you updated the price of both the drums and the guitar! So you set the LP as the new parent for both instruments. Update its neighbors. Ok, you inally have a price for the piano, by trading the guitar for the piano. So you set the guitar as the parent. Finally, the last node, the drum set. Rama can get the piano even cheaper by trading the drum set for the piano instead.
Now, as I promised, you need to igure out the path. To start with, look at the parent for piano. So you follow this edge. Piano has drums as its parent. And drums has the LP as its parent. So Rama will trade the LP for the drums. By following the parents backward, you now have the complete path. It can be about minimizing something. In this case, Rama wanted to minimize the amount of money he spent.
Negative-weight edges In the trading example, Alex ofered to trade the book for two items. How would you show this on the graph? Now Rama has two ways to get to the poster. Now, if you remember, Rama can trade the poster for the drums. Negative-weight edges break the algorithm. First, make the table of costs. Next, ind the lowest-cost node, and update the costs for its neighbors.
In this case, the poster is the lowest-cost node. Update the costs for its neighbors. But you just found a cheaper way to the poster! Here are the inal costs. Bellman-Ford is out of the scope of this book, but you can ind some great explanations online. First, you need to implement the graph. For example, Start has two neighbors, A and B. Why not just use another hash table? What if you want to ind the weights of those edges? Implementation he full graph hash table looks like this.
Next you need a hash table to store the costs for each node. You know it takes 2 minutes from Start to node B. You know it takes 6 minutes to get to node A although you may ind a path that takes less time. Can you represent ininity in Python? Implementation Find the node with the lowest cost. Get the cost and neighbors of that node. Loop through the neighbors. Each node has a cost. Update the cost. How long does it take to get to the inish if you go through node B?
It takes 7 minutes. Implementation Set the new cost and the new parent for the Finish node. Ok, you updated the costs for all the neighbors of node B. Mark it as processed. Find the next node to process. Get the cost and neighbors for node A. Currently it takes 7 minutes to get to the Finish node.
How long would it take to get there if you went through node A? I hope the walkthrough helped you understand the algorithm a little better. You get a list of classes. You want to hold as many classes as possible in this classroom. How do you pick what set of classes to hold, so that you get the biggest set of classes possible?
Sounds like a hard problem, right? Actually, the algorithm is so easy, it might surprise you. Pick the class that ends the soonest. Now, you have to pick a class that starts ater the irst class. Again, pick the class that ends the soonest. Art ends the soonest, at a. Now you need the next class that starts ater a. English is out because it conlicts with Art, but Math works. Finally, CS conlicts with Math, but Music works.
A greedy algorithm is simple: at each step, pick the optimal move. In this case, each time you pick a class, you pick the class that ends the soonest. Believe it or not, this simple algorithm inds the optimal solution to this scheduling problem! But you can only take what you can it in your knapsack. What algorithm do you use? Again, the greedy strategy is pretty simple: 1. Pick the most expensive thing that will it in your knapsack.
