Data Structures and Algorithms
An algorithm is a set of instructions that should be followed to achieve an end goal. They are specific to computing, but we often talk about algorithms to accomplish a certain task in a computer program. When we write computer programs, we generally implement algorithms. For example, when we wish to sort an array or list of numbers, we usually come up with an algorithm to do so. It is a core concept in computer science and important for any good programmer to understand. We have algorithms for sorting, searching, graph problems, string processing, and many more. Java comes with a number of algorithms already implemented for you. However, we still have the scope to define our own.
A data structure is a way to store and organize data in order to facilitate access and modifications. An example of a data structure is an array used to hold several items of the same type or a map used to hold key-value pairs. No single data structure works well for all purposes,...
