Problem I: Write a complete Go program whose main function spawns a fan of rn goroutines and synchronizes them, without busy waiting, so that they cooperatively alternate printing ping pong to standard error, where n is given as a command-line argument. Each line must be printed to standard error by a different goroutine, and no goroutine must printmore than once. The goroutines need not print in the order in which they are created. For instance, S go run PingPongFan. go 10 1 ping // printed by goroutine9 2 pong // printed by goroutine 5 3 ping // printed by goroutine3 4 pong // printed by goroutine 4 5 ping // printed by goroutine 2 pong // printed by goroutine 6 7 ping // printed by goroutine 7 8 pong// printed by goroutine 8 ping // printed by goroutine 1 10 pong /l printed by goroutine 10 Your program must not contain any race conditions. Do not give more than 25 lines of code.
