WebDec 23, 2016 · pathSum (root, sum, false) The idea is that if the sum has been tampered i.e a node value on the path has already been deducted, we are no longer allowed to pass it as-is to the branch below the node. So, we set tamperedSum to true whenever we deduct the node value from the sum as: sum - root.value. WebDec 28, 2016 · You are given a binary tree in which each node contains an integer value (which might be positive or negative). Design an algorithm to count the number of paths that sum to a given value. The path does not need to start or end at the root or a leaf, but it must go downwards (traveling only from parent nodes to child nodes).

number of paths in a binary tree with a given sum

WebGiven 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 and sum = 22, 5 / \ 4 8 / / \ 11 13 4 / \ \ 7 2 1 return true, as there exist a root-to-leaf path 5->4->11->2 which sum is 22. WebNov 1, 2014 · I've programmed an algorithm to return the weight of the heaviest path from the root of a binary tree to one of its leaves. Each Node in the tree has a weight (its data). The weight of the path is the sum of all of the Nodes weights from root to leave inclusive. This algorithm finds the heaviest. highway to mount fansipan
