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. Web下载pdf. 分享. 目录 搜索
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.
