Palindrome Number
- Given an integer x, return true if x is palindrome integer.
- An integer is a palindrome when it reads the same backward as forward.
- For example, 121 is palindrome while 123 is not.
Example 1:
Input: x = 121
Output: true
Example 2:
Input: x = -121
Output: false
Explanation:
- From left to right, it reads -121.
- From right to left, it becomes 121-.
- Therefore it is not a palindrome.

My Solution
def isPalindrome(x):
pal_num = str(x)
while len(pal_num) > 1:
head = pal_num[0]
tail = pal_num[-1]
pal_num = pal_num[1:-1]
if head != tail:
return False
return True
