Calculate the Function Time Limit: 2 Seconds Memory Limit: 65536 KB You are given a list of numbers A1 A2 .. AN and M queries. For the i-th query: The query has two parameters Li and Ri. The query will define a function Fi(x) on the domain [Li,…
思路:容易得到s[n]=s[n-1]+s[n-2],也就是fib数. 求第k小的fib质数的也就是第k个质数数-2,当k>2时. 在就是s[n]/x%m=s[n]%(x*m)/x. 代码如下: #include<cstdio> #include<algorithm> #include<cstring> #define ll long long #define M 1000005 using namespace std; ll k,x,m; int prime[M]…
Vasya is studying number theory. He has denoted a function f(a, b) such that: f(a, 0) = 0; f(a, b) = 1 + f(a, b - gcd(a, b)), where gcd(a, b) is the greatest common divisor of a and b. Vasya has two numbers x and y, and he wants to calculate f(x, y).…
