C++ program to find count of divisors in n!
Copy the below C++ program and execute it with the help of GCC compiler. At the end of this program, We have shared the output of this program.
#includeusing namespace std; typedef unsigned long long int ull; vector allPrimes; // Fills above vector allPrimes[] for a given n void sieve(int n) { // Create a boolean array "prime[0..n]" and // initialize all entries it as true. A value // in prime[i] will finally be false if i is // not a prime, else true. vector prime(n+1, true); // Loop to update prime[] for (int p=2; p*p The post C++ program to find count of divisors in n! appeared first on FreeWebMentor.
