[LeetCode] Plus One

Given a non-negative number represented as an array of digits, plus one to the number.

The digits are stored such that the most significant digit is at the head of the list.

class Solution {public:    vector<int> plusOne(vector<int> &digits) {         reverse(digits.begin(), digits.end());         int i = 0, c = 0;         digits[0] += 1;         while(i < digits.size())         {             int tmp = digits[i] + c;             digits[i] = tmp % 10;             c = tmp / 10;             i++;         }         if(c == 1)            digits.push_back(1);         reverse(digits.begin(), digits.end());         return digits;    }};

怎么看着略蛋疼呢，好像用STL做太简单了。。。额
