Shuffle List

Rearrange the values in a list in random order.

Examples in Go
package main

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

func main() {
	rand.Seed(time.Now().UnixNano())
	a := []int{1, 2, 3, 4, 5}
	for i := len(a) - 1; i > 0; i-- {
		j := rand.Intn(i + 1)
		a[i], a[j] = a[j], a[i]
	}
	fmt.Println(a)

	// You can also use rand.Shuffle
	b := []int{6, 7, 8, 9, 10}
	rand.Shuffle(len(b), func(i, j int) {
		b[i], b[j] = b[j], b[i]
	})
	fmt.Println(b)
}
