Given two integers N and D, Find a set of N integers such that the difference between their product and sum is equal to D.
Examples:
Input : N = 2, D = 1 Output : 2 3 Explanation: product = 2*3 = 6, Sum = 2 + 3 = 5. Hence, 6 - 5 = 1(D). Input : N = 3, D = 5. Output : 1 2 8 Explanation : Product = 1*2*8 = 16 Sum = 1+2+8 = 11. Hence, 16-11 = 5(D).
A tricky solution is to keep the difference D to choose N numbers as N-2 ‘1’s, one ‘2’ and one remaining number as ‘N+D’.
Sum = (N-2)*(1) + 2 + (N+D) = 2*N + D.
Product = 1*2*(N+D) = 2*N+2*D
Difference = (2*N+2*D) – (2*N+D) = D.
