What’s leetcode? In my interviews they usually ask me to write pseudocode solutions to some fun, clever little problems. Like, one asked me to write a function to get the permutations of a list of arrays of strings. That one took me a few minutes to solve- should have been obvious but I did stare into space for a minute or two before giving the answer. I think I was just nervous. That was the hardest one though, all the others were easy. But you know, aside from just knowing what you’re doing I don’t know how you would grind to prepare for that.
