To check prime numbers, we declare a function isPrime() that will return 1, if number is prime and return 0 if number is not prime. Then, in main() function – we are using a loop with 0 to len-1 (total number of array elements) and calling isPrime() by passing array elements on...

Implemented with a frequency array, you can count this in O(2^6) time for each i. (Read editorial for https://codeforces.com/contest/547/problem/C if you still need help working out the details.) Then, using the above count, you can find any a[i] such that the number of coprime...
The product in each step could be MOD’ed by the BASE to produce a remainder, and that remainder could be used to look up a bit. This is the same process that was discussed earlier when determining if the number was prime. Instead the method has an array of pre-computed bytes ...

bitset是类模板,实例化时需指定一个模板非类型参数,表示有多少个bit。实例化后大小固定,类似array 由于位集合的大小是模板参数,故必须是constexpr bitset中的二进制位是匿名的,通过位置编号访问。最低位编号为0,最高位对应最大编号 用unsigned 值初始化 bitset ...
