9. Palindrome Number

// soal dibawah
function palindrome(n) {
    const reverse = n.toString().split("").reverse().join("");
    
    if(n == reverse) {
        return true;
    } else {
        return false;
    }
}

console.log(palindrome(-121))

/*
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.
