Given the running logs of n functions that are executed in a nonpreemptive single threaded CPU, find the exclusive time of these functions. Each function has a unique id, start from 0 to n-1. A function may be called recursively or by another functio…
这个函数真的很强大,这篇随笔也将一直更新一些总结,直到涵盖大多数应用: eg1: 今天公司项目中从云端获取了一段字符串---"+CBC: 0,90,4090" 我想获取其中的数字0,90,4090.我们当然可以写一个函数,判断,并且逐一取值,然后再糅合成想要的数据,但是这样也真的太麻烦了,于是sscanf就来了. #include<stdio.h> int main(void) { int a; int b; int c; char *s="+CBC: 0,90,…
