Palindrome in Go

Palindrome in Go

A palindrome is a number/string which is similar when read from the front and from the rear.

Problem statement
Given an Number, check whether it is palindrome or not.

Solution

package main

import "fmt"

func checkPalindrome(num int) bool {
	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 true
	} else {
		return false
	}
}

func main() {
	if checkPalindrome(122) {
		fmt.Println("Number is palindrome")
	} else {
		fmt.Println("Number is not palindrome")
	}

}

Problem statement
Given a string, check whether it is palindrome or not.

Solution

package main

import "fmt"

func isPalindrome(str string) bool {
	for i := 0; i < len(str); i++ {
		j := len(str) - 1 - i
		if str[i] != str[j] {
			return false
		}
	}
	return true
}

func main() {

	if isPalindrome("ana") {
		fmt.Println("String is palindrome")
	} else {
		fmt.Println("String is not palindrome")
	}

}
