You will write a program that uses fork) to create two child processes that will play rounds of RPS. The child processes will wait until the parent "signals" (Note: you don't actually need to use UNIX signals to do this, you can use your chosen IPC methods) that they should choose their next "throw." The children should repeat this wait-throw-wait proce ss until they are signaled to exit. The parent process should output each child's process id and, for each round, output each child's throw" and the result of the round. After the tournament is over, the parent should output the aggregate re sults. For example S/rps1 3 Child 1 PID: 113 Child 2 PID: 114 Beginning 3 Rounds... Fight! Round 1 Child 1 throws Scissors Child 2 throws Rock! Child 2 Wins! Round 2: Child 1 throws Paper Child 2 throws Scissors Child 2 Wins Round 3 Child 1 throws Paper! Child 2 throws Rock Child 1 Wins! Results: Child 1: 1 Child 2: 2 Child 2 Wins
