This tutorial will show you how to implement a hash table with separate chaining. It’s not the most efficient method, but it is the simplest way to get started and create a fully functioning hash table.
You may hate the line at the DMV, but without it, things might turn into a rough-and-tumble free for all! In the same way that a line keeps raging motorists from getting out of hand, a Queue helps your computer keep its ducks in a row. The Queue functions very much like a line of people. It’s a First-In, First-Out (FIFO) data structure, so no cutting!
Need a quick run down on a classic data structure? Look no further.
A linked list is an ordered collection of elements. The thing that makes it special is how it stores data. Behind the scenes, each number, string, object, or other value you may need to keep track of is stored in a Node. Each Node references its successor.
There’s no other data structure like the Stack. In only a few minutes, you can have a fully working implementation that can be used to solve a wide variety of problems. Stacks are useful for anything from reversing a string to language processing applications – not to mention the fact that many programming languages (and probably your operating system) rely on a Stack to function.
