(d)scanArray: This function makes no sense to me in the context of a sieve. If 1 indicates a prime number, why would you indiscriminately mark "unknown" numbers as "prime"? Are you sure the description for this
The first line contains two positive integers n and x (1 ≤ n ≤ 105, 2 ≤ x ≤ 109) — the size of the array and the prime number. The second line contains n space-separated integers a1, a2, ..., an (0 ≤ a1 ≤ a2 ≤ ... ≤ ...

In this problem, we are given an odd number N. Our task is to express an odd number as the sum of prime numbers. There can be at max three prime numbers while expressing the number. Let’s take an example to understand the problem, Input: N = 55 Output: 53 + 2 Solution Approach...

The primes occur when the zeros in the a, b, c, d pattern across a row line up. It is just fun. I was looking at was the idea codable to then look for the number that does not fit the pattern. That is the purpose of Fortran. Translate 0 Kudos Copy link Reply mecej4 ...

We create a boolean array of size equal to the given number (N) and mark each position in the array True. We initialize a variablepequal to 2 andsequal to 0. If the variablepis prime then mark each multiple of number False in the array. ...
