Palindrome Numbers

• A number is palindrome if its reverse is same as number.
• Number is >=0
• A single digit number is always a palindrome number.

Input: n = 12321 Output: Yes

Input: n = 2332 Output: Yes

Input: n = 5 Output: Yes

Input: n = 34 Output: No

Input: n = 123 Output: No

Implementation

package main

import (
    "fmt"
)

func main() {
    // res := isPalindrome(12321) // true
    // res := isPalindrome(1221) // true
    res := isPalindrome(123) // false
    fmt.Println(res)
}

func isPalindrome(n int) bool {
    rev := 0
    temp := n
    for temp != 0 {
        lastDigit := temp % 10
        rev = rev*10 + lastDigit
        temp = temp / 10
    }
    return rev == n
