Python实现分页式存储系统位示图内存分配，附输入输出逻辑及注意点

以下是用 Python 实现的代码： ```python import math # 定义位示图 bitmap = [0] * 64 # 标记已占用的块 occupied_blocks = [1, 3, 5, 7, 9, 11, 13, 15, 17, 19] for block in occupied_blocks: bitmap[block] = 1 # 处理输入的进程申请内存块数 process_requests = list(map(int, input().split())) # 处理输入的进程编号和页面号 process_info = list(map(int, input().split())) def find_free_block(): """ 查找空闲块 """ for i in range(64): if bitmap[i] == 0: bitmap[i] = 1 return i return -1 # 没有空闲块 def handle_process(process_id, request_count, page_number): """ 处理进程请求 """ allocated_blocks = 0 for _ in range(request_count): free_block = find_free_block() if free_block == -1: # 没有足够空间 print("wait") return allocated_blocks += 1 if page_number >= request_count * 8: # 页号错误 print("error") return block_number = (allocated_blocks - 1) * 8 + page_number print(block_number) handle_process(process_info[0], process_requests[process_info[0] - 1], process_info[1]) ``` 额外需要注意的逻辑点： 1. 对于位示图的操作要确保准确，避免出现重复分配或错误标记的情况。 2. 在处理页面号时，要仔细判断其是否超出进程申请的内存块范围。 3. 注意输入数据的合法性检查，比如进程编号和申请的内存块数是否在合理范围内。 ######[AI写代码神器 | 443点数解答 | 2024-12-02 10:54:23]
