This diagram shows an example of memory configuration under dynamic partitioning, after a number of placement and swapping-out operations have been carried out. Addresses go from left to right;, gray areas indicate blocks occupied by processes, white areas indicate free memory blocks. The last process placed is 2-Mbyte and ismarked with an X. Only one process was swapped out after that. 4M 8M IM 3M a. What was the maximum size of the swapped-out process? b. What was the size of the free block just before it was partitioned by X? c. A new 3-Mbyte allocation request must be satisfied next. Indicate the intervals of memory where a partition will be created for the new process under the following four placement algorithms: best-fit, first-fit, next-fit, and worst-fit. For each algorithm, draw a horizontal segment under the memory strip and label it clearly
