Golang : Sort and reverse sort a slice of integers
Problem :
How to sort and reverse sort a slice of integers ?
Solution :
Use sort.Ints and sort.Sort functions.
package main
import (
"fmt"
"sort"
)
var intSlice = []int{4, 3, 2, 1, 0}
func main() {
fmt.Println("Original : ", intSlice[:])
sort.Ints(intSlice)
fmt.Println("Sort : ", intSlice)
sort.Sort(sort.Reverse(sort.IntSlice(intSlice)))
fmt.Println("Reverse Sort : ", intSlice)
}
Output :
Original : [4 3 2 1 0]
Sort : [0 1 2 3 4]
Reverse Sort : [4 3 2 1 0]
NOTE : There is a 3rd party package that can be used for sorting as well. See http://godoc.org/github.com/cznic/sortutil and https://www.socketloop.com/tutorials/golang-sort-and-reverse-sort-a-slice-of-bytes on how to use the sortutil
package
