Task 1: Design a program Gym Management System using Linked List System Details:- These are the module the system should have: a. Client registration, Insert new client, Update client information, monitors attendance. b. The gym schedule for each client, program able to assign gym schedule, update attendance and monitor the progress of a client. c Diet schedule for each client, assign the diet chart to a client, monitors client progress, updates diet taken by the client and display progress. Task 2: Complexity Analysis - Theoretically discuss and compute the complexity of all important algorithms that you implemented. The discussion will describe your understanding of the algorithm. Put the complexity on a table as shown in Table 1. Table 1: Complexity Analysis Algorithm Algorithm 1 Algorithm 2 Complexity Odlog n) (n)
