问题: 设计一函数,求整数区间[a,b]和[c,d]的交集.(c/c++.Java.Javascript.C#.Python) 1.Python: def calcMixed(a,b,c,d): rtn=[] list1=range(a,b+1) for num in range(c,d+1): if num in list1: rtn.append(num) return rtn mixed=calcMixed(1,8,5,9) print(mixed) 2.

Carmichael Numbers An important topic nowadays in computer science is cryptography. Some people even think that cryptography is the only important field in computer science, and that life would not matter at all without cryptography. Alvaro is one
洛谷P1440 求m区间内的最小值 ............................................................................... 以上代表我此时的心情,调了一个小时....只因为顺序,维护一个单调递增队列就好了,这里n很大,输出要优化,这才挽救了30分.. #include<bits/stdc++.h> using namespace std; int n,m; ],q[]; int top,tai; void Cin(int
