The prime counting function is the function pi (x) giving the number of primes less than or equal to a given number x (Shanks 1993, p. For example, there are no primes <=1, so pi (1)=0. [1][2] It is denoted by π(x) (unrelated to the number π). . A new proof has brought mathematicians one step closer to understanding the hidden order of those “atoms of arithmetic,” the prime numbers. 15). Tool for counting prime numbers via the prime-counting function denoted pi (n) which counts the prime numbers less than or equal to a real number n. Example 1: Input: n = 10 Output: 4 Explanation: There are 4 prime numbers less than 10, they are 2, 3, 5, 7. Count Primes - Given an integer n, return the number of prime numbers that are strictly less than n.
