Given an integer `x`

, return `true`

* if *`x`

* is a * *palindrome**, and *`false`

* otherwise*.

Example 1:

Input: x = 121 Output: true Explanation: 121 reads as 121 from left to right and from right to left.

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.

Example 3:

Input: x = 10 Output: false Explanation: Reads 01 from right to left. Therefore it is not a palindrome.

Constraints:

`-231 <= x <= 231 - 1`

Follow up: Could you solve it without converting the integer to a string?

__ Code(Python):-__

class Solution(object):

def isPalindrome(self, x):

if x<0:

return False;

else:

a=x

rev=0

while(a!=0):

r=a%10

a=a//10

rev=rev*10+r

if rev==x:

return True

else:

return False
