@TheLittleNaruto no, I only know a little bit about trees, and I don't know jack about graphs. I am very bad at recursion as well, and at other things, I can only solve easy problems.
I mean I am not able to understand if you can solve easy ones, then what is the point to start looking for a job from next month ? Or are you implying that by next month you'll be ready enough ?
@TheLittleNaruto lol, I won't be ready ever, if you ask me. I am just trying my luck actually. Either I'll get more prepared, or I'll land a better job. Both are just fine for me
