Palindrome Number Easy
Problem Statement
Given an integer `x`, return `true` if `x` is a palindrome, and `false` otherwise.
An integer is a palindrome when it reads the same backward as forward.
For example, `121` is a palindrome while `123` is not.
Input Format
A single integer `x`.
Output Format
Print `true` if the number is a palindrome, `false` otherwise.
Constraints
- -2^31 <= x <= 2^31 1
Examples
Example 1
Input
121
Output
true
Explanation: 121 reads as 121 from left to right and from right to left.
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.
