[leetCode] 9. Palindrome Number (Python)

Determine whether an integer is a palindrome. An integer is a palindrome when it reads the same backward as forward.

 

Example 1:

Input: 121
Output: true

Example 2:

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

 

Follow up:

Coud you solve it without converting the integer to a string?

 

Solution

class Solution:
    def isPalindrome(self, x: int) -> bool:
        x = list(str(x))
        
        return x == x[::-1]
