A real coder should not be satisfied by doing only one problem daily, rather he/she should keep coding as much as possible. So, here I (@MadhavBahlMD) am adding some more problems that you can practise 😃

Also, these problems have been taking form various sources, so ig you think you own any of the given problems, just send me an email at theleanprogrammer@gmail.com and I will be more than happy to give proper credits 😊

Want to contribute?

The file structure is as follows

\DAILY CODE BASE
├───BONUS
│   ├───Algorithms
│   ├───Arrays
│   ├───Graphs
│   ├───LinkedLists
│   ├───Queues
│   ├───Recursion
│   ├───Stacks
│   ├───Strings
│   └───Trees

In this main README.md, there are links to the README of BONUS directory, and the README.md of sub topics In the README.md of BONUS directory, there is the list of all topics and under that there are all questions In the README.md of any topic directory, say Arrays there is a README which contains all questions of that topic along with the link to the README.md of the directory containing the question The README.md of directory containing the question must contain all the information about the question with some examples and the solution, and a little writeup about the algorithm used.

Before contributing any question, make sure that this structure is followed properly

NOTE

In case you just want to contribute a question and not code, there is no need to do so many things, just open an issue with the topic Problem Submission and the problem in the comments. I'll add it myself, and will give you proper credits 😃
