The leetcode grind is very real these days. My advice for people is pick a language you want to get more familiar with but have a decent understanding of already. It will help you learn some of the standard but not always used libraries. For example I’m doing some in Python now and had never used the defaultdict class, even though I’ve been using python for 10+ years.
