    My solution followed the same idea after got "time limit exceeded" from my initial DP solution, but yours is obviously much clearer and cleaner. Admire!
    lol and found a benefit of using a bit slower language - always force you to find a better solution. If I were using C++ etc maybe the DP solution would pass with no problem and I'll satisfy with that while miss a smarter solution like this!
