public class Solution {
    public int reverse(int x) {
        int result = 0;

        while (x != 0) {
            if (Math.abs(result) > Integer.MAX_VALUE / 10) {
                return 0;
            }
            int mod = x % 10;
            result *= 10;
            result += mod;
            x /= 10;
        }

        return result;
    }
}
