Very well done Alexander!
Tour of Go
Foster variables are the evil offspring of 'bad thing'! #rant
func fibonacci() func() int {
i, j := 0, 1
return func() int {
k := i + j
i = j
j = k
//...
}
}
func RunFibo() {
f := fibonacci()
for i := 0; i < 10; i++ {
fmt.Println(f())
}
}
Alarm Clock
By using the main thread for a Remind
-task, you don't have to create a forever waiting WaitGroup
.
Your code:
func Remind(text string, delay time.Duration) {
for {/*...*/}
}
func main() {
var wg sync.WaitGroup
wg.Add(3)
go func() {
Remind("time to eat", 10*time.Second)
wg.Done()
}()
go func() {
Remind("time to work", 30*time.Second)
wg.Done()
}()
go func() {
Remind("time to sleep", 60*time.Second)
wg.Done()
}()
wg.Wait()
}
With three threads:
func Remind(text string, delay time.Duration) {
for {/*...*/}
}
func main() {
go Remind("time to eat", 10*time.Second)
go Remind("time to work", 30*time.Second)
Remind("time to sleep", 60*time.Second)
}
Concurrent Sum
I forgive you for the pattern duplication.
Keep it up!
