Question 2 The factorial of a positive integer, n, denoted by n!, is the product of all positive integers less than or equal to n, i.e. n! = n x (n - 1) ( n - 2) x (n - 3) .... x 3 x 2 x 1. For example: 5! = 5 x (5 - 1)*( 5 2) (5 3) x (5 4) = 5 x 4 x 3 x 2 x 1 = 120 Using a while loop control structure, write your own function called my.factorial to compute the factorial value for any given integer, n. Your code must: be preceded by the pseudocode only use the R base library (no external packages) consist of appropriate control structure(s) provide correctly defined function(s) be fully commented run without error [TOTAL 10 MARKS]
