Reverse digits of an integer.

Example1: x = , return

Example2: x = -, return -

class Solution {

public:

    int reverse(int x) {

        // Start typing your C/C++ solution below

        // DO NOT write int main() function

        if(x == ) return x;

        int flag = ;

        if(x < )

        {

            x*= -;

            flag = -;

        }

        vector<int> result;

        while(x)

        {

          int temp = x %;

          result.push_back(temp);

          x/=;

        }

        int num = ;

        for(int i = ; i< result.size(); i++)
