Count Primes - Given an integer n, return the number of prime numbers that are strictly less than n. View JatinYadav96's solution of Prime Arrangements on LeetCode, the world's largest programming community. The logic of the sieve of Eratosthenes is pretty simple. The multiples of a given prime are generated as a sequence of numbers starting from that. If it is assumed that the time taken to mark a number as composite is constant, then the number of times the loop runs is equal to: On taking n common from the above equation, the above equation can be rewritten as: It can be proved as below with the help of Harmonic.
