Find the number of ways a number can be expressed as a sum of primes?
Test Case: Number 7 can be wrtten as 2+2+3, 2+3+2, 2+5, 3+2+2, 5+2 in 5 ways.
This is last year's Nutanix interview question which I came across while sitting for campus placements. It's been one year since I saw the question. Still couldn't figure out how to solve the problem. Any help is really appreciated!!
