Part Two: Programming Questions (3 x 20 marks)

1. (20 marks) By definition the Greatest Common Divisor (GCD) of two integers M and N is an integer that is the greatest among the numbers that can divide both M and N. Write a web page with embedded PHP scripts that can find out the GCD of M and N (both are non-zero), which are input from the user. The found GCD shall be displayed in the HTML5 table along with the M and N, as well as all other common divisors for people to check that the number is indeed a GCD. In the form for users to input M and N, JavaScript should be used to

validate the input to make sure it is a non-zero integer number.

2. (20 marks) Create an XML document that marks up the structure of COMP 466, up to

sections, and then create an XML schema to describe the structure of your XML document.
