摘要：def calculate_response_time(C, queries):response_time = float('inf')for T, MaxRespCode in queries:# 计算 MaxResponseTimeif MaxRespCo

若 MaxRespCode

若 MaxRespCode >= 128，则使用位运算计算：exp = (MaxRespCode >> 4) & 0x07（取高3位）mant = MaxRespCode & 0x0F（取低4位）MaxRespTime = (mant | 0x10)

初始设定 response_time = T + MaxResponseTime

遍历每个查询报文：计算 current_response_time = T + MaxResponseTime取最小的 response_time = min(response_time, current_response_time)
