2673. Make Costs of Paths Equal in a Binary Tree

LeetCodeArrayDynamic ProgrammingGreedyTreeBinary TreeOpen on judge ↗

You are given an integer n representing the number of nodes in a perfect binary tree consisting of nodes numbered from 1 to n. The root of the tree is node 1 and each node i in the tree has two children where the left child is the node 2 * i and the right child is 2 * i + 1. Each node in the tree also has a cost represented by a given 0-indexed integer array cost of size n where cost[i] is the co
