At the root level, there is a folder for each language in which I have solved Leetcode problems.
In each language folder, there is a file for each problem I have solved in that language. The filename specifies the problem number and name, as specified in Leetcode.
In each problem file, I place each of my solutions, one after another, with comments seperating them. If I only solved it once, I do not have a specific identifying comment for the solution. There is a comment at the top specifying problem URL.
