LeetCode

Collection of LeetCode questions to ace the coding interview! - Created using LeetHub

Explore my new experiences about coding Data structures & Algorithms and solving the various problems including my new techniques of algorithms to solve them both efficiently and worthlessly.

It would be too difficult for me to take Hard difficulty, so I've done only Medium and Easy (most likely easy) difficulty.

If you have some free time and willingly want to teach someone about Data struct & Algo. Don't hesitate to contact me na.

Enjoy!!! 😋
