Very elegant method to generate and utilize created optimal scores from the left. This solution is very fast and nearly linear with size.
It is not close to linear. Richard, since he is using the function max for every number. It is at least O(n^2), in which n is size, and maybe even a little bit more since he is using indexing, another comparison(besides max), creating new arrays and so on. His code is small and functional though: kudos.
