Palindrome Checker Program in Go

In this article, the palindrome checker program is created with Go programming language.

This is the steps to check if the sentence is a palindrome.

1. Split the sample sentence into many characters.
2. Create a reversed string from the splitted characters.
3. Check the reversed and sample string. If the reversed is equals to sample string then it is a palindrome. Otherwise, it is not a palindrome.

This is the implementation in Go.

func isPalindrome(sample string) bool {
    // create a variable to store reversed string
    var reversed string

    // split sample string
    var words = strings.Split(sample, "")

    // insert all characters from the last index
    // into "reversed" variable
    for i := len(words) - 1; i >= 0; i-- {
        reversed += words[i]
    }

    // if sample is equals to reversed string
    // then the result is true
    if sample == reversed {
        return true
    }

    // return false if sample is not equals to reversed string
    return false
}

The isPalindrome() function is used in main function.

package main

import (
    "fmt"
    "strings"
)

func main() {
    // return true
    fmt.Println(isPalindrome("level"))

    // return false
    fmt.Println(isPalindrome("sample text"))
}

Output

true
false
