When users click "Execute" button, the browser makes a request to /sum using Post method (TheServlet is configured in web.xml) (0.5 point):
a. Check validate input n:
- If users input a value is not an integer number > 5, show the error text "You must input an integer> 5" to servlet. (0.5 point)
- If users do not choose any option, show the error text "You must choose an option" to servlet.(0.5 point)
b.Execute:

servlet (Example: n=6 output: 9). (0.5 point)- If users choose "Sum even" option, sum the even numbers from 1 to n, then output the result to servlet (Example: n=6→ output: 12). (0.5 point)
