class Solution(object):
    def isPalindrome(self, x):
        if x < class="syntax-number">0:
            return False
        
        original = x
        reversed_number = class="syntax-number">0
        
        while x > class="syntax-number">0:
            last_digit = x % class="syntax-number">10
            reversed_number = reversed_number * class="syntax-number">10 + last_digit
            x = x class=class="syntax-string">"syntax-comment">// class="syntax-number">10
        
        return original == reversed_number

solution = Solution()
print(solution.isPalindrome(class="syntax-number">121))
print(solution.isPalindrome(-class="syntax-number">121))
print(solution.isPalindrome(class="syntax-number">10))
