3. Using Pool() do the following: 3.1. The pool must have 2 processes, each process will pass two parameters to a search function, these parameters must be the name of the file and a word to search for, these two parameters must be entered by the user and must be different from the process to another. 3.2. The Search function must search for the word in the file and if the word is found then find out the number of occurrences for this word otherwise return that the word doesn't appear in the file. 3.3. You need to verify that the file the user inserted is actually a file and it exists in the system.
