3. Use the following major Memory Allocation schemes to solve the given problem: The memory partitions given are 200KB,400KB,600KB,500KB,300KB and 250KB (in order). Apply the first-fit, best-fit, and worst-fit algorithms to place processes of 350KB,215KB,470KB and 490KB (in order) to the given memory partitions. a. First-fit b. Best-fit c. Worst-fit 2of4 d. Which algorithm makes the most efficient use of memory? [2.0 marks]
