Given the root of a binary tree, calculate the vertical order traversal of the binary tree. For each node at position (row, col), its left and right children will be at positions (row + 1, col - 1) and (row + 1, col + 1) respectively. The root of the tree is at (0, 0)....
Binary Tree Vertical Order Traversal https://leetcode.com/problems/binary-tree-vertical-order-traversal/ 这道题让我们竖直的遍历树,和按层遍历非常相似。我第一次做的时候,使用的是递归的形式,发现顺序会出错。 因此还是要借助按层遍历的思路,将树逐层的加入一个队列,然后再取出来进行处理。 遍历的时候,...
