Given a binary tree, return the vertical order traversal of its nodes' values. (ie, from top to bottom, column by column). If two nodes are in the same row and column, the order should be from left to right. Examples:Given binary tree [3,9,20,null,nu

根据题目要求打印出需要的输出格式. 这算是些趣味题目了,题目本身不难,要说难点就是考如何优雅地去编程了,主要是考编程基础功力. 而且好像测试系统不是十分严格,并不判断后面多余的空格,按题目要求是需要严格去掉后面多余的空格的. 处理这个问题就需要多点代码了. 下面看我使用一个额外的数组spaceHeight[ALP_LEN[来解决这个问题,做到半个多余的空格符也没有. #include <cstdio> #include <string.h> const int MAX_N = 75
