Leetcode tricks in Swift

It’s time for another article. This time I am going to talk about a really fun puzzle game I’m sure we have all played. Leetcode. Now, I have no affiliation with Leetcode. But, I really love the programmer puzzles that this site provides. It might seem like a time sink, but, I feel like it sharpens your skills a little while also giving you a fun brain teaser. It’s also great preparation for interviewing.
