A dynamic memory partitioning scheme is being used and the following is the memory configuration at a given point in time (partition sizes are in MB. A Allocated. F:Free Partition 0 starts at address 0 in memo Partition # | 0 | 1-2 10 11 40 40 AIF 4 6 9 size 20 20 40 60 20 10 60 4020 30A A/F The next each of the three blocks using the foll 3 memory requests are for 10MB, 20 MB, and 40 MB. Indicate the starting address for owing placement algorithms. Show your work. a) Best-fit b) First-fit c) Worst-fit
