                1. Replace "Your_STUDENT_ID" string with your 9 digits student ID //const STUDENT_ID = 'Your_STUDENT_ID';
                2. Make sure all your functions are in Your_Student_id-functions.js and is in the same directory as main1.html 
                The tester script will automatically load your js file.
                3. Check your function for any syntax error before using the tester script. Any error caused by your function will stop the tester script.
                4. There should only be one console.log() statement per function. No document.write, No innerHTML , No alert and No extra output in console.
