The “odd/even factorial” of a positive integer n is represented as n!! and is defined recursively as: a. (n)*(n-2)*(n-4)………*(2) if n is even. For example, 6!! = 6*4*2 = 48 b. (n)*(n-2)*(n-4)*…….*(5)*(3)*(1) if n is odd. For example, 7!! = 7*5*3*1 = 105. Come up with a recursive definition for n!! and use it to guide you to write a method definition for a method called “oddevenfact” that recursively calculates the odd/even factorial value of its single int parameter. The value returned by “oddevenfact” is a long.

Question
The “odd/even factorial” of a positive integer n is represented as n!! and is defined
recursively as:
a. (n)*(n-2)*(n-4)………*(2) if n is even. For example, 6!! = 6*4*2 = 48
b. (n)*(n-2)*(n-4)*…….*(5)*(3)*(1) if n is odd. For example, 7!! = 7*5*3*1 = 105.
Come up with a recursive definition for n!! and use it to guide you to write a method definition
for a method called “oddevenfact” that recursively calculates the odd/even factorial value of its
single int parameter. The value returned by “oddevenfact” is a long.
