题目描述在图论中,包含n个结点(结点编号为1~n)、n-1条边的无向连通图被称为树。 在树中,任意一对结点间的简单路径总是惟一的。 你拥有一棵白色的树——所有节点都是白色的。接下来,你需要处理c条指令: 修改指令(0 v):改变一个给定结点的颜色(白变黑,黑变白); 查询指令(1 v):询问从结点1...

题目:
Given a binary tree containing digits from 0-9 only, each root-to-leaf
path could represent a number.
An example is the root-to-leaf path 1->2->3 which represents the number 123.
Find...

Given two binary strings, return their sum (also a binary string).
For example,
a = "11"
b = "1"
Return "100".
求数字字符串的二进制和。同之前的数组代表数字,两个数组相加一样,只不过进位变成了2.可能两个串的长度不一样,故逆转,从左到右加下去,最后再逆转。
