加位与进位。模拟。
[Code]
1: vector<int> plusOne(vector<int> &digits) {
2: // Start typing your C/C++ solution below
3: // DO NOT write int main() function
4: int cary=1, sum =0;
5: vector<int> result(digits.size(),0);
6: for(int i = digits.size()-1; i>=0; i--)
7: {
8: sum = cary+digits[i];
9: cary = sum/10;
10: result[i] = sum%10;
11: }
12: if(cary >0)
13: {
14: result.insert(result.begin(), cary);
15: }
16: return result;
17: }
