Algorithm to find which number in a list sum up to a certain number http://stackoverflow.com/questions/3420937/algorithm-to-find-which-number-in-a-list-sum-up-to-a-certain-number I will explain it using a recursive function and memoization which is easier to understand than a bottom up approach... calls which leads to an O 2^n algorithm. Now we can apply memoization to make it run in time O n S which is faster if S is.. time O n S which is faster if S is not too big def f v i S memo if i len v return 1 if S 0 else 0 if i S not in memo # Check..
