给两个长度分别为n和m的序列，现在有两种操作：1.分别选择两个序列的一个非空前缀，切两个前缀的最后一位相同，删除之，得到1分（只累计），消耗e；2.直接删除两个序列，消耗值定于两个序列之前删除的元素个数之和，并且使得得到的分有效（之前没有有效分）
(1?≤?n,?m?≤?105; 1?≤?s?≤?3·105; 103?≤?e?≤?104)，s代表总能量，e表示一次操作的消耗...

Given two binary strings, return their sum (also a binary string).
For example,
a = "11"
b = "1"
Return "100".
思路同十进制的大数相加。代码如下：
class Solution {
public:
string addBinary(string a, str...
