An Algorithms is a step by step procedure for solving a problem or a finite set of sequence of specified actions for solving a problem or sequence of steps performed by computer to solve a problem. You can define it as easy you can but the sole purpose should remain same.

Algorithms are widely used in IT industry for processing data, calculation, modifying data and much more. Algorithms can be explained in any language, from natural languages like English to programming languages and also using flowcharts.

Flowcharts: A flowchart is the graphical representation of an algorithm. Flow chart contain various boxes connected with arrows in order to illustrates a solution model to a given problem.

In this guide you will study various algorithms like Analysis of Algorithms, Searching, Sorting, Greedy Algorithms, Divide and Conquer, Graph Algorithms, Randomized Algorithms, Branch and Bound etc and their practical approach in various languages.
