**Note:**
The input is assumed to be a 32-bit signed integer. Your function should **return 0 when the reversed integer overflows**.

## Code

    public int reverse(int x){
        long result = 0;
        while(x!=0){
            int temp = x%10;
            result = result*10+temp;
            x/=10;
        }
        if (result>Integer.MAX_VALUE||result
