Can you solve this real interview question? Count Primes - Given an integer n, return the number of prime numbers that are strictly less than n.

The closest gap between any pair is 2, which can be achieved by [11,13] or [17,19]. Since 11 is smaller than 17, we return the first pair.

You are given an integer n . We say that two integers x and y form a prime number pair if: 1 <= x <= y <= n; x + y == n; x and y are prime numbers.

(Recall that an integer is prime if and only if it is greater than 1, and cannot be written as a product of two positive integers both smaller than it.)

16 дек. 2021 г. · Problem statement. Given an integer n, return the number of prime numbers that are strictly less than n. Example 1: Input: n = 10. Output: 4

To solve this problem, we can use the Sieve of Eratosthenes algorithm, which is an efficient algorithm for finding all prime numbers up to a given limit.
