浙大 编程能力测试 的甲级题目 第 1016. Phone Bills (25) 电话账单统计问题 繁杂的题目 但是其实并不难 思维条理很简单的-A long-distance telephone company charges its customers by the following rules:



Making a long-distance call costs a certain amount per minute, depending on the time of day when the call is made. When a customer starts connecting a long-distance call, the time will be recorded, and so will be the time when the customer hangs up the phone. Every calendar month, a bill is sent to the customer for each minute called (at a rate determined by the time of day). Your job is to prepare the bills for each month, given a set of phone call records.
