Hardest problem to solve so far: describing 30min trivial problems turned out to be much less fun than I imagined.
- Problem #8: binary tree (fun, but always same)
- Problem #9: array operations (boring and always same)
- Problem #10: go basics (3 lines wtf)
- Problem #11: a search tree
- Problem #12: recursive algorithm (always same, sometimes hard to detect)
- Problem #13: string operations (super lame)
I will keep updating GitHub, but not sure about the website.
