Web9 Sep 2024 · So, sum = 10 and product = 24. Recommended: Please try your approach on {IDE} first, before moving on to the solution. Naive Approach: A simple solution is to traverse the array and keep checking for every element if it is composite or not and also divisible by k then add and product the composite element at the same time. Web22 Feb 2024 · If n is even, then n is the sum of 4, which is composite, and n − 4, which is even (a multiple of 2), hence composite, provided n > 6. If n is odd, then n is the sum of 9, which is composite, and n − 9, which is even (a multiple of 2), hence composite, provided n > 11. Share Cite Follow answered Feb 22, 2024 at 5:38 J. W.
