# Question ---->

# 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.


# Answer ---->

                return False
            
            i+=1
            j-=1
        
        return True

        :type x: int
        :rtype: bool

# Result ---->

# Your input:
# 121

# Output:
# true

# Expected:
# true
