I cannot believe that summing challenge has been on the site for twenty minutes and got 4 downvotes but no one even bothered to add the fastest algorithm tag. Don't just downvote, fix.
asymptotic time complexity. (definition) Definition: The limiting behavior of the execution time of an algorithm when the size of the problem goes to infinity. This is usually denoted in big-O notation. See also asymptotic space complexity.

f=lambda n,s,h=0:h^n and-~f(n,s[1:],h+[h/~h,1,-h][ord(s[0])%4])
For example, f(4, 'UDDUURUUUUUUUDDDD') is 10.
