a)Suppose we have 1000K of memory where the first 100K is reserved. Also suppose that the following processes have been allocated memory in the following order: P1: 100K, P2: 100K, P3: 25K, P4: 200K, P5: 200K, P6: 75K, P7: 100K. Create a diagram of memory.

b)Suppose that P2, P4, and P6 finish and the following processes are on the queue waiting for memory (assume FIFO): P8: 150K, P9: 25K, P10: 50K, P11: 25K. Create a diagram of memory for each of the following algorithms showing how the memory would be allocated: First-Fit, Best-Fit, Worst-Fit.
