Py3 C++ DP速解1320  Minimum Distance to Type a Word Using Two Fingers

這題確實有難度，最初的解答是3D DP，然後逐次化簡，化成2D後，大該就已經是極致了，不想用hash map，300x (26+1)也不大，0ms C++ code

-----

This problem is indeed challenging. The initial solution was 3D dynamic programming, which was then simplified to 2D, reaching its limit. I didn't want to use a hash map; 300x (26+1) isn't a large number. 0ms C++ code.
