2415. Reverse Odd Levels of Binary Tree

LeetCodeTreeDepth-First SearchBreadth-First SearchBinary TreeOpen on judge ↗

Given the root of a perfect binary tree, reverse the node values at each odd level of the tree. - For example, suppose the node values at level 3 are [2,1,3,4,7,11,29,18], then it should become [18,29,11,7,4,3,1,2]. Return the root of the reversed tree. A binary tree is perfect if all parent nodes have two children and all leaves are on the same level. The level of a node is the number of edge
