Your task is to convert this program to a multithreaded version. your program should take an integer p> 0 as the command-line argument (do sanity checks, ). you are going to create p threads (in additiona to the main thread) that divide the 65,536 number of combinations among them (more or less). for example, if p=3, each thread would be responsible for roughly 65,536/3 number of iterations (if it's not divisible, some threads can end up with one more iteration than the others).
