The project details are in the pdf file. I want to edit this code in order to pass the testcases correctly. The first part (Queue implementation in queue.hpp) passes the testcases correctly. Therefore, it needs no edit. Parts two and three do not pass the testcases. The problem is probably in the code logic. Also, I am not allowed to use any data structures other than the C array. A tip will be provided in case of correct answer.
