Think you're smart? Then crack it!

You think you are smart in programming? In job place, everyone seems seek you for the answer whenever there's a problem? Then go and try : crackthecode, by MSDN Canada.

And the prize is (who knows, maybe Microsoft Canada is hiring potential developer?):

And now for the bounty: Two $500 Future Shop gift cards can be won on April 29, 2008 and May 15, 2008. The $4000 Grand Prize gift card draw will be on June 13, 2008. The winners will receive a call, so keep an eye on your phone.

While I was trying yesterday, I only managed to answer first and third questions correctly.

Here are some hints:
Question 1: The answer got something to do with what you see when you entered the page! And I solved it.

Question 2: (I do not know. Most of my time was doing windows programming! Maybe you can download Microsoft Script Debugger and see, or even Visual Studio 2005/2008???)

Question 3 : This is a mathematics question, all those C-like languages programmer should be able to answer it easily. What's a waste to put this as question 3. :( And I lost my key because of slow Internet connection, WTF!

Question 4 : (I do not have the key!)

Maybe I need to apply another hotmail account! And it's your turn now.
