[ENVIRYO2112VIT]

Hello @aaryahjolia I am planning to contribute into this repsitory under GSSoC'23 ! I have certain coding questions from LeetCode, CodeStudio, etc. which have been part of earlier interviews of Moderate to Hard level. I would like to share with them in your repository.

I assure you with

• Clean code
• Ellaborate approach explanation with comments
• Properly named variables.

Some of problems examples are:

• Binary Search:Book Allocation Problem, Aggressive Cows
• Arrays

Please assign me with this issue, I would be glad to be working in this 😄
