Given two binary strings, return their sum (also a binary string).
For example,
a = "11"
b = "1"
Return "100".
字符串表示二进制数，求相加后的结果
C++（6ms）：
1 class Solution { 2 public: 3 string addBinary(string a, string b) { 4 string res = "" ; 5 int c = 0 ; 6 int i = a.size()-1 ; 7 int j = b.size()-1 ; 8 while(i >= 0 || j >= 0 || c == 1 ){ 9 c += i >= 0 ? a[i--]-‘0‘:0 ; 10 c += j >= 0 ? b[j--]-‘0‘:0 ; 11 res = char(c%2 + ‘0‘) + res ; 12 c /= 2 ; 13 } 14 return res ; 15 } 16 };
