LeetCode.872-叶子值相等的树(Leaf-Similar Trees) 这是悦乐书的第334次更新,第358篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第204题(顺位题号是872)。考虑二叉树的所有叶子,从左到右的顺序,这些叶子的值形成叶子值序列。 例如,在上面给定的树中,叶子值序列是(6,7,4,9,8)。 如果两...
Leetcode872.Leaf-Similar Trees叶子相似的树 请考虑一颗二叉树上所有的叶子,这些叶子的值按从左到右的顺序排列形成一个 叶值序列 。 举个例子,如上图所示,给定一颗叶值序列为 (6, 7, 4, 9, 8) 的树。 如果有两颗二叉树的叶值序列是相同,那么我们就认为它们是 叶相似 的。 如果给定的两个头结点分别为...
Two binary trees are considered leaf-similar if their leaf value sequence is the same. Return true if and only if the two given trees with head nodes root1 and root2 are leaf-similar. Note: Both of the given trees will have between 1 and 100 nodes. 题意:给定两棵树,每棵树的叶子序列...
