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…
