Dashboard - 2017 Benelux Algorithm Programming Contest (BAPC 17) - Codeforces 大意：给n个数字，求区间gcd的情况数 首先，设我们有三个数字 a b c gcd(a,b)==d，gcd(b,c)==e，gcd(d,e)==f 因为gcd(b,b)==b，gcd(gcd(a,b),gcd(b,c))=gcd(a,b,c,d)=gcd(a,b,c) 所以我们可以

Goldbach's conjecture is one of the oldest unsolved problems in number theory and in all of mathematics. It states: Every even integer, greater than 2, can be expressed as the sum of two primes [1]. Now your task is to check whether this conjecture h
