The factorial of a positive integer N, denoted by N!, is defined by the following: N! = 1 * 2 * ..... * N (Note: 0! = 1) Using module and/or functions, create a recursive program to compute N!. The user should input a positive integer and a subprogram should check that the input is correct ( a positive integer). Then use recursion to computer the factorial. Create a subprogram that will call itself to do the multiplication until N = 1. Then display the result in the main program. You must submit both the pseudocode and the flowchart for this assignment. Save your flowchart and pseudocode in the same document (PDF or doc) then drop them into the assignment dropbox. Draw a flowchart and write a pseudocode for the complete program, main module and a subprograms and/or functions. After completing this assignment drop it into the assignment drop box.
