There are two types of processes, WriterP and ReaderPs. WriterP process is responsible from writing the latest local news on news.txt placed on disk at directory /tmp. There are 6 ReaderP processes. Write Pseudo code for syncing all of the processes under the following conditions;

When WriterP writes the local news, no other processes can access to the file.

WriterP only writes to the file after all (i.e. 6) ReaderPs completely read the file.

You can use ReaderP #id for sequential reading.. (i.e. ReaderP1 then ReaderP2 then ReaderP3...)

a. [20] Use only Signals for synchronizing. (Only two Signal Types are enough ?)

b. [20] Use only Semaphores for synchronizing (Only two semaphore int values are enough?)

Discuss the reasons you have given and give the necessary details....
