Write a Golang program to check whether a given number is a palindrome or not

Definition: A palindrome is a number which is similar when read from the front and from the rear.

Examples

• num = 121 => Palindrome
• num = 13131 => Palindrome
• num = 123 => Not a Palindrome

Approach to solve this problem

• Step 1: Define a function that accepts a numbers(num); type is int.
• Step 2: Start making the number from the input number.
• Step 3: If the given number is same as the output number, then return “Palindrome”
• Step 4: Else, return “Not A Palindrome”

Program

Live Demo

package main import "fmt" func checkPalindrome(num int) string{    input_num := num    var remainder int    res := 0    for num>0 {       remainder = num % 10       res = (res * 10) + remainder       num = num / 10    }    if input_num == res {       return "Palindrome"    } else {       return "Not a Palindrome"    } } func main(){    fmt.Println(checkPalindrome(121))    fmt.Println(checkPalindrome(123))    fmt.Println(checkPalindrome(1331))    fmt.Println(checkPalindrome(1231)) }

Output

Palindrome Not a Palindrome Palindrome Not a Palindrome
