归并排序
归并排序是建立在归并操作上的一种有效的排序算法。该算法是采用分治法(Divide and Conquer)的一个非常典型的应用。
算法步骤:
1. 申请空间,使其大小为两个已经排序序列之和,该空间用来存放合并后的序列
2. 设定两个指针,最初位置分别为两个已经排序序列的起始位置
3. 比较两个指针所指向的元素,选择相对小的元素放入到合并空间,并移动指针到...

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。
