Given a positive integer, n, return a, b, c and d, such that

1. n = a*2^b+c*3^d

2. a, b, c and d are all positive integers greater than 1

If a solution does not exist, set all four output variables to zero.

Example 1:

n = 26

a = 2

b = 2

c = 2

d = 2

Example 2:

n = 28

a = 0

b = 0

c = 0

d = 0
