Here I would be sharing the code I wrote for the problems posted on LeetCode.

Most problems took time for me to write the working code & optimize that. So I am giving some of those here as I solve Hard/Medium/Easy problems on LeetCode. I think, like me, many people would be able to understand the problems & come up with possible solution quickly, but during implementation are lost in the middle. So check the code given here & get the idea & write your own code your own way...Cheers!
