题目如下: 解题思路:本题和括号匹配问题有点像,用栈比较适合.一个元素入栈前,如果自己的状态是“start”,则直接入栈:如果是end则判断和栈顶的元素是否id相同并且状态是“start”,如果满足这两个条件,则说明这个元素和栈顶的元素是配对的,栈顶元素出栈.但是这个函数的的执行时间却不能简单的用end-start,因为这个函数里面可以还调用了其他函数,需要减去这些内部调用函数的执行时间,这里就需要引入一个新的变量来保存内部调用函数的执行时间.这个时间也很好求,函数完成配对后,栈顶元素出栈,只要…

On a single threaded CPU, we execute some functions.  Each function has a unique id between 0 and N-1. We store logs in timestamp order that describe when a function is entered or exited. Each log is a string with this format: "{function_id}:{"s…
2018-04-28 14:10:33 问题描述: 问题求解: 个人觉得这是一条很好的模拟题,题目大意就是给了一个单线程的处理器,在处理器上跑一个函数,但是函数里存在调用关系,可以是调用其他函数,也可以是递归的调用自己,通过logs给出每个函数的开始和结束时间,问每个函数的实际运行时间是多少.logs是按时间戳的顺序给的,并非按照函数名,最后的结果需要按照函数名的大小排序后给. 为什么说这是一条模拟题呢,因为函数的调用关系本质上就是栈中的压栈出栈,使用栈这个数据结构能够很好的模拟函数的调用关系,…
