This is a GoLang exercise: a. Create two go-routines, which are running a loop with 10 iterations. Find a way to make the execution slower. b. How do you get data from those routines in the “main thread” ? c. Receive 10 individual strings from each go-routine. d. Find a way to stop the running go-routines from the “main thread”

		panic("Panic in the middle panic")
