it. the problem is how many ways an integer n can be written as the sum of at least two positive integers. for example, take n = . the number can be written as + + + + + + + + + + + + + here's a solution for given $n$. # zero-based array (first index is ) ways = [ , , ..., ] (n zeroes) for i in , ..
., n- : for j in i, ..., n: ways[j] = ways[j] + ways[j-i] print ways[n] this solution is elegant and efficient, but unfortunately, i do not understand the logic. can someone please explain the logic of this solution to the problem?...
