I need help explaining how to do this problem in depth.

Question 4a 18 Points] Given the following information about the current state of main memory, determine the memory locations to which two processes Pl and P2 requiring 6.5K and 4K memory, respectively, should be allocated based on (i) Best-fit strategy and (ii) Worst-fit strategy. You must first allocate memory to P1 and then to P2. Show the status of the memory after the allocation (for P2) in each case. Current memory status: 0-6K allocated; 6K-12K: Free; 12K-24K allocated; 24K-35K Free; 35K-40K allocated; 40-55K Free
