An official Trane course for learning to solve LeetCode problems. The questions were selected from neetcode.io. Shout out to them for going over the work of organizing a subset of Leetcode questions by topic and difficulty. You can watch a video answer for all the questions in these courses on their site.

As you progress through the first exercises, Trane will automatically move on to questions of a higher difficulty while also reminding you to review questions you have seen before.

Unlike an exercise asking you to perform a piece of music or to solve a chess puzzle, the problems in these courses are more open-ended. What solving the problem means is up to you. You could force yourself to code the solution from scratch every time you are shown a problem, but this could get old soon. You could also code it the first time, and just draft a solution in pseudocode afterwords. Or you could simply review the solution and assign yourself a score based on how much of it you remembered.
If you are stuck on a problem, it's OK to look at the solution. Just make sure you assign yourself a low score (1 or 2).
