I have been programming for about 3 years. And just I have realized I know nothing about it. You may be surprised! But believe me, I have learnt a little about data structures and algorithms. To say the very truth, they are the heart of programming. So I should learn them as many as I can.

The time doesn’t wait. But fortunately, I have time to learn till now. You may start with me too. I am making a list of data structures and algorithms so that anyone can easily know what to learn. But I have a disclaimer. Please use this list with your common sense. I am not showing any learning source here. Because, I will implement in Python3, you may use C/C++/Java. So please search on Google/Bing to get the resources. Also I may make some mistakes to categorize these things. Adjust kindly!
