Golang : Sort and reverse sort a slice of floats




Problem :

How to sort and reverse sort a slice of floats ?

Solution :

Declare the slice type as sort.Float64Slice and use Sort() method and sort.Reverse functions.

 package main

 import (
 "fmt"
 "sort"
 )

 var floatSlice sort.Float64Slice = []float64{4.22222, 1.5555, -6.55555, 99.889888}

 func main() {

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

 floatSlice.Sort()

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

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

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

 }

Output :

Original : [4.22222 1.5555 -6.55555 99.889888]

Sort : [-6.55555 1.5555 4.22222 99.889888]

Reverse : [99.889888 4.22222 1.5555 -6.55555]
