Solutions are uploaded as .cpp files, complete with write-ups commented at the top of each file.
Write-ups contain the following sections, if applicable:
- Problem - a summary of the problem
- Implementation - an explanation of the solution
- Time complexity - the big-O time complexity of the solution, along with an explanation of why the solution suffers from that worst-case time complexity.
- Space complexity - the same as above, except for space instead of time.
- What could be done better? - An explanation of any improvements that might be made to the solution.
