Problem $1.$ Design an algorithm for an application that orders a product and finds its total price before and after

Tax. First, you should check for the validity of the input $($Make sure to enter positive numbers$).$ When the user

specifies the quantity to order, the application should:

Check the availability of the product

Compute the Net Total Price with Tax $(20\%)$ only if the ordered quantity is available. Otherwise, give the

following error message "Sorry! This order is not currently available".

Design the algorithm and the corresponding Raptor flow chart by specifying the problem input, output, and

drawing the corresponding flowchart on Raptor.

Problem $2.$ Design an algorithm to calculate the area and circumference of a rectangular field. Your answer

should specify the following:

Input$($s$)$

Output$($s$)$

Statement$($s$)$

Corresponding Raptor Flowchart$($s$)$ including any constraints on the input values $($Validity check$).$
