plz. i don't have much time. thank you.

Question 2 The factorial of a positive integer, n, denoted by nl, is the product of all positive integers less than or equal to n, i.e. n! = nx (n-1) (n - 2) (n - 3) .... x 3 x 2 x 1. For example: 51 = 5x (5 - 1)* ( 5 - 2) (5 - 3) (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]
