单选题：consider an operating system that manages the main memory with t
consider an operating system that manages the main memory with the variable-sized multiple-partition method. Given free memory partitions of 100K, 500K, 200K, 300K, and 600K (in order), how would this operating system place processes of 212K, 417K, 112K, and 426K (in order) by using Worst-fit memory allocation algorithms? @[C](1)
