Alexander Kaiser: 10题是不是有问题 p是指针数组 赋值不应该是p[0]吗

2301_81045780: For a sequentially stored linear list of lengthN, which of the following operations has the time complexityO ( 1 )? A. visit thei-th (1≤i≤N) node and find the immediate predecessor of thei-th (2≤i≤N) node B. insert a new node after thei-th (1≤i≤N)node C. delete thei-th (1≤i≤N)node D. sort the N nodes in increasing order

2301_78243210: a=int(input()) b=int(input()) c=int(input()) print(b*b-4*a*c) 这样写可以吗～

Tuenity: 前面把不是素数的排除了，然后还剩下1和素数，因为1不是素数，所以需要特判一下

awaiiii: if(num!=1): return True 大佬，这里是什么意思呀，不等于1就返回是素数了嘛，不是得同时满足嘛
