Reverse digits of an integer.

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

class Solution{
public:
    int reverse(int x)
    {
        long t=0;
        while(x!=0)
        {
            t=t*10+(x%10);
            x/=10;
        }
       return (t>INT_MAX||t<INT_MIN)?0:(int)t;
    }
};
