Question:
Determine whether an integer is a palindrome. Do this without extra space.

My Solution: Note:
1. "palindrome" means "the integer" is equal to "the reverse_integer"
2. to reverse integer (loop) Step1: %10, Step2: *10, Step3: /10
while( temp_integer !=0){
int tail = temp_integer % 10;
reverse_integer = reverse_integer * 10 + tail;
temp_integer = temp_integer / 10; 
}
3. if "the reverse_integer" is equal to "the integer"
if(reverse_integer == x)
return true;
