Golang : Sort and reverse sort a slice of bytes

Problem :

How to sort and reverse sort a slice of bytes ?

Solution :

Import "github.com/cznic/sortutil"

Use the ByteSlice type ( see http://godoc.org/github.com/cznic/sortutil#ByteSlice ) and invoke the Sort() method.

 package main

 import (
 "fmt"
 "github.com/cznic/sortutil"
 "sort"
 )

 var bytes sortutil.ByteSlice = []byte("zxvfbac")

 func main() {

 // Bytes
 fmt.Println("Original : ", string(bytes[:]))
 fmt.Println("Original : ", bytes[:])

 sort.Sort(bytes)

 fmt.Println("Sort : ", string(bytes[:]))
 fmt.Println("Sort : ", bytes[:])

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

 fmt.Println("Reverse : ", string(bytes[:]))
 fmt.Println("Reverse : ", bytes[:])

 }

Output :

Original : zxvfbac

Original : [122 120 118 102 98 97 99]

Sort : abcfvxz

Sort : [97 98 99 102 118 120 122]

Reverse : zxvfcba

Reverse : [122 120 118 102 99 98 97]
