Leetcode rotate integer

Reverse digits of an integer.

Example1: x = 123, return 321
Example2: x = -123, return -321

class Solution {

public:
    int reverse(int x) {
        // Start typing your C/C++ solution below
        // DO NOT write int main() function
        int value=0;
        int flag=1;
        if(x==0)
        return value;
        
        if(x>0)
        flag=1;
        else
        flag=-1;
        
        x=abs(x);
        while(x>0)
        {
            
            int temp= x%10;
            x=x/10;
            value*=10;
            value+=temp;
        }
        return value*flag;
    }
};
