Go Slice Shuffle

myshuffle.go

package main

import (
    "fmt"
    "math/rand"
    "time"
)

func Shuffle(a []int) {
    for i := range a {
        j := rand.Intn(i + 1)
        a[i], a[j] = a[j], a[i]
    }
}

func main() {
    a := []int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
    rand.Seed(time.Now().UnixNano())
    Shuffle(a)
    fmt.Println(a)
}

Take a look at rand.Perm -- might save the need to call rand.Int inside the loop.
