Solution: Write Code with Livelock

package main
import (
	"fmt"
	"sync"
	"time"
	"runtime"
)
func main() {
	runtime.GOMAXPROCS(4)
	type value struct {

		value1 string
		value2 string
		locked bool
	}
	lock := func(v *value) {

		v.locked = true
	}
	unlock := func(v *value) {
		v.Unlock()
		v.locked = false
	}
	move := func(wg *sync.WaitGroup, v1, v2 *value) {
		defer wg.Done()
		for i := 0; ; i++ {
			if i >= 3 {
				fmt.Println("canceling goroutine...")
				return
			}
			fmt.Printf("%v: %v \n", v1.id, v1.value1)
			lock(v1) // <1>
			time.Sleep(2 * time.Second)

				continue
			}
		}
	}
	a, b := value{
		id: "Alice", 
		value1: "I am picking up spoon",
		value2: "Alice is hungry", 
	}, value{
		id: "Bob", 
		value1: "I am picking up spoon",
		value2: "Bob is hungry",
	}
	
	var wg sync.WaitGroup
	wg.Add(2)
	go move(&wg, &a, &b)
	go move(&wg, &b, &a)
	// go move(&wg, &a, &b)

	wg.Wait()
}
