Reverse Integer

Reverse Integer

Reverse digits of an integer.

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

public class Solution {
    public int reverse(int x) {
        int result = 0;
        boolean flag_neg = false;
        if(x < 0){
            flag_neg = true;
            x = -x;
        }
        while(x != 0){
            int temp = x % 10;
            result = result * 10 + temp;
            x /= 10;
        }
        if(flag_neg)
            result = -result;
        return result;
    
    }
