Sorting algorithms/Sleep sort: Difference between revisions

=== Using sync.WaitGroup ===

<lang go>package main

import (

"fmt"

"log"

"os"

"strconv"

"sync"

"time"

)

func main() {

var wg sync.WaitGroup

wg.Add(len(os.Args[1:]))

for _,i := range os.Args[1:] {

x, err := strconv.ParseUint(i, 10, 64)

if err != nil {

log.Println(err)

}

wg.Add(1)

go func(i uint64, wg *sync.WaitGroup) {

defer wg.Done()

time.Sleep(time.Duration(i) * time.Second)

fmt.Println(i)

}(x, &wg)

}

wg.Wait()

}</lang>

Usage and output are the same as the version using channels. Note that the original version would sleep for increments of 1 full second, so I made my code do the same.
