This problem was to be solved in an iterative or recursive fashion, reducing a cube with side length to a cube with side length
, and continuing. However, once we repeat this process enough times, we'll end up with two cases: a cube with side length 0 or 1. For the cube with side length 0, we are done. For the cube with side length 1, we can simply add 1 to the
6 counter.
Time complexity: . The constraints were purposely left small to allow for
solutions to pass.
Alternatively, if you're up to it, try thinking of an O(1) solution for this problem! (This was originally the original constraint for the problem 😊)
