Reverse Integer

Reverse digits of an integer.

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

  int reverse(int x) {

   if(x == 0)
    return 0;
   bool isneg = false;
   
   if(x  < 0)
   {
    x  = -x;
    isneg = true;
   }

   int result  = 0; 
   while(x)
   {
    int t  = x % 10;
    x  = x / 10;
    result = result * 10 + t;
   }


   if(isneg)
    return -result;
   else
    return result;

}
