Given a n-ary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. Nary-Tree input serialization is represented in their level order traversal, each group of children is separated by the null value...

Given a n-ary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. For example, given a3-arytree: We should return its max depth, which is 3. Note: The depth of the tree is at most1000....

LeetCode算法题-Maximum Depth of N-ary Tree(Java实现) 这是悦乐书的第261次更新,第274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128题(顺位题号是559)。给定n-ary树,找到它的最大深度。最大深度是从根节点到最远叶节点的最长路径上的节点数。例如,给定一个3-ary树: 我们应该返回...
LeetCode559. Maximum Depth of N-ary Tree 第一次写出了具有迭代和递归的函数,还是有点收获的,虽然题目比较简答 当要对某些对象重复使用时,考虑循环,也就是迭代 当函数可以简化一个重复的操作时,考虑递归,而且就当下一次使用这和函数的结果已经有啦,就不会考虑的太复杂 自己写的答案: 反思学习: 1.对list不知...
