package main

import (
	"fmt"
	"runtime"
	"sync"
	"time"
)

func main() {
	runtime.GOMAXPROCS(2)

	var wg sync.WaitGroup
	wg.Add(3)
	go func() {
		defer wg.Done()
		var i int
		for {
			i++
		}
	}()

	go func() {
		defer wg.Done()
		var i int
		for {
			i++
		}
	}()

	time.Sleep(time.Second)
	go func() {
		defer wg.Done()
		fmt.Println("Here I am!")
	}()


	wg.Wait()
}
