Golang : Sort and reverse sort a slice of strings




Sometimes we will want to sort or reverse sort a collection of strings alphabetically. It is pretty easy to sort a slice of strings in Go. Just declare the slice as type sort.StringSlice and use the Sort method.

Here’s an example of sorting slice of Strings in Go.

 package main

 import (
 "fmt"
 "sort"
 )

 var strSlice sort.StringSlice = []string{"apple", "durian", "kiwi", "banana"}

 func main() {

 fmt.Println("Original : ", strSlice[:])

 strSlice.Sort()

 fmt.Println("Sort : ", strSlice[:])

 sort.Sort(sort.Reverse(strSlice[:])) 

 fmt.Println("Reverse : ", strSlice[:])

 }

Output :

Original : [apple durian kiwi banana]

Sort : [apple banana durian kiwi]

Reverse : [kiwi durian banana apple]
