Approach (Brute Force) The general approach is to check for every integer less than N and increment the result if they are prime. For example, consider N = 10. Now, we can run a check from 2 to N – 1 to find how many primes lie in this range. But, this approach requires a prime check on the whole range, [2, N – 1].
