Sort Array of Strings in Golang

Application

Create new folder named src. In src folder, create new file named main.go as below:

package main

import (
	"fmt"
	"strings"
)

func main() {

	var names = [5]string{"mary", "peter", "kevin", "anna", "johny"}

	result1 := SortASC(names)
	fmt.Println("Sort ASC")
	fmt.Println(result1)

	result2 := SortDESC(names)
	fmt.Println("Sort DESC")
	fmt.Println(result2)

}

func SortASC(a [5]string) [5]string {
	for i := 0; i < len(a)-1; i++ {
		for j := i + 1; j < len(a); j++ {
			if strings.Compare(a[i], a[j]) > 0 {
				temp := a[i]
				a[i] = a[j]
				a[j] = temp
			}
		}
	}
	return a
}

func SortDESC(a [5]string) [5]string {
	for i := 0; i < len(a)-1; i++ {
		for j := i + 1; j < len(a); j++ {
			if strings.Compare(a[i], a[j]) < 0 {
				temp := a[i]
				a[i] = a[j]
				a[j] = temp
			}
		}
	}
	return a
}

Output

Open Terminal windows in Visual Studio Code and run command line: go run main.go
