Changes

While parallel processing of multiple threads increases program performance, it makes debugging task harder, since we need to track multiple threads instead of just one (Master thread). Also some potential bugs are introduced with parallel processing, for example, when race condition (When multiple processes or threads try to access same resource at the same time, for more information visit [https://en.wikipedia.org/wiki/Race_condition Race Condition Wiki]) occurs and mutual exclusion is performed incorrectly, it may create a deadlock condition (When all threads wait for the resource and none can execute, for more info visit [https://en.wikipedia.org/wiki/Deadlock Deadlock Wiki]), which can be very difficult to debug.
