Reverse digits of an integer.

Example1: x = 123, return 321

Example2: x = -123, return -321

 

public class Solution {    public int reverse(int x) {                if(x==Integer.MIN_VALUE)  return 0;         long result = 0;        int i = 0;                int temp = (x>0)?1:0;        x = Math.abs(x);                    while(x != 0){            result *= 10;            result +=  x%10;            x /= 10;            if(result > Integer.MAX_VALUE || result < Integer.MIN_VALUE) return 0;        }        return (temp==1)?(int)result:(int)-result;                    }}
