Here you will find a list of coding challenges / problems / exercises I have did for fun, along with some thoughts and discussions, which hopefully would be helpful to someone who is also enjoying the excitement of solving fun coding challeneges :)

• HR: HackerRank
• LC: LeetCode

Aside from these coding exercises, I have also benefited greatly from the following books back when I prepared for interviews, which I sincerely recommend you taking a look as well if you are or will be preparing for an interview.

The classic:
