Algorithms are simply step-by-step algorithms for fixing issues, and most of those problems have already been solved, examined and verified by someone. You can, of course, dive into the deep philosophy of the genius Knuth, study multi-page tomes with proofs and justifications, but do you wish to spend your time on this?

About the book

I (Aditya Bhargava) First of all, I tried to make the guide straightforward to read. I keep away from unexpected turns; every time a brand new idea is mentioned in the guide, I either clarify it right away or say the place I will explain it. Core ideas are reinforced with workout routines and re-explanations so you'll have the ability to take a look at your assumptions and ensure you don't lose the thread.

Many examples are offered throughout the book. My aim is not to dump a bunch of obscure formulation on the reader, but to simplify the visual presentation of those ideas. I additionally imagine that we be taught best once we can remember something we already know, and examples help refresh our reminiscence. So, when you assume about how arrays differ from linked lists (Chapter 2), just take into consideration looking for company seats in a movie theater. You could have already realized that I am a supporter of the visible type of studying - the book is stuffed with drawings.

The contents of the book have been rigorously thought out. It is senseless to write down a guide describing all sorting algorithms - there are sources similar to Wikipedia and Khan Academy for this. All algorithms described within the book are of practical value. I have used them in my work as a programmer, and they provide a great foundation for learning more superior matters.

Who is this e-book for

This book is for readers who know the basics of programming and wish to perceive the algorithms. Perhaps you've already encountered a programming problem and are trying to find an algorithmic solution.

Or perhaps you want to perceive the place algorithms can come in handy. The following is a brief and partial record of people that may profit from the guide:

—self-taught programmers;

—students who've begun to be taught programming;

—graduates who want to refresh your reminiscence;

- physicists/mathematicians/other disciplines interested in programming.
