Two processors P1 and P2 receive data X and Y respectively from two satellites, square the data, then send the result to a third processor P3 to calculate their sum. Each of P1 and P2 has only an input buffer for one data item while P3 has a buffer for two data items. In the diagram below, the circles represent processors and the boxes represent buffers. Write a correct concurrent program using binary semaphores to synchronize the operations of the three processors
