Golang вопросы собеседований

👣 Что выведет код ?

package main

func oneStep(yield func() bool) {
 yield()
}

func f() {
 for range oneStep {
  print("f ")
  recover()
 }
}

func g() {
 for range 1 {
  print("g ")
  recover()
 }
}

func checkPanic(loop func(), c chan<- struct{}) {
 defer func() {
  println(recover() != nil)
  c <- struct{}{}
 }()
 defer loop()
 panic(123)
}

func main() {
 c := make(chan struct{}, 1)
 go checkPanic(f, c)
 <-c
 go checkPanic(g, c)
 <-c
}
