思路：与数字反转思路一样，可直接解答

class Solution:
    def isPalindrome(self, x: int) -> bool:
        y = abs(x)
        nums = 0
        while (y!=0):
            num = y%10
            nums = nums*10 + num
            y = y//10
        if x == nums and x>=0:
            return True
        else:
            return False
