Q3]A dynamic partitioning scheme is being used, and the following is the memory configuration at a given point in time: 40M 60M 20M 10M 60M 40M 20M 30M 40M 40M The shaded areas are allocated blocks; the white areas are free blocks. The next three memory requests are for 40M, 20M, and 10M. Indicate the starting address for each of the three blocks using the following placement algorithms: a. First-fit b. Best-fit c. Next-fit. Assume the most recently added block is at the beginning of memory. d. Worst-fit
