### Your mission is to find the starting number that is less than 1,000,000 with the longest sequence.
This might take a long time. To make it faster, you might cache previous
answers. Suppose you have an array prev[]. Prev[n] is the length of the
answers. Suppose you have an array `prev[]`. `Prev[n]` is the length of the
sequence starting at n. If, when computing a sequence, you ever get to a
number with a value in `prev[]`, you can use that instead of continuing the
computation.
