In the program below, we've used a recursive function recur_sum() to compute the sum up to the given number. Source Code # Python program to find the sum of natural using recursive function def recur_sum(n): if n <= 1: return n else: return n + recur_sum(n-1) # change this...

[leetcode] path sum @ Python [recursion] Given a binary tree and a sum, determine if the tree has a root-to-leaf path such that adding up all the values along the path equals the given sum. For example: Given the below binary tree andsum = 22, 5 / \ 4 8 / / \ 11 13 4 /...

A better exponential-time algorithm usesrecursion. Subset sum can also be thought of as a special case of the0–1 Knapsack problem. For each item, there are two possibilities: Include the current item in the subset and recur for the remaining items with the remaining total. ...
