二进制字符创相加，通过进位的方式逐位考虑。也可以把相加的过程抽象成一个函数。
Given two binary strings, return their sum (also a binary string).
For example,
a = "11"
b = "1"
Return "100".
方法一：
class Solution {
public:
s...

设两个数组分别为A和B，size为as和bs。原问题可以转化为两个排序数组求第k大的问题。
还是两种思路：
比较A[as/2]和B[bs/2]，每次抛弃A或者B的一半
代码如下：
double findMedianSortedArrays(int A[], int m, int B[], int n) {
int total = m + n;
if (tot...
