WebJan 24, 2024 · Count of subarrays from an array of length M is equal to M * (M + 1) / 2. Therefore, from a given array, a contiguous subarray of length M consisting only of primes will generate M * (M + 1) / 2 subarrays of length. Traverse the array and for every element check if it is a prime or not. For every prime number found, keep incrementing count. This is a list of articles about prime numbers.
