In a binary tree, the root node is at depth0, and children of each depthknode are at depthk+1. Two nodes of a binary tree arecousinsif they have the same depth, but have different parents. We are given therootof a binary tree with unique values, and the valuesxandyof two different...

今天介绍的是LeetCode算法题中Easy级别的第235题(顺位题号是993)。在二叉树中,根节点在深度0处,并且每个深度为k的节点的子节点,他们深度为k + 1。 如果二元树的两个节点具有相同的深度但具有不同的父节点,则它们是堂兄弟。 我们给出了具有唯一值的二叉树root,以及树中两个不同节点的值x和y。
