I guess incomplete is better than an F...

...especially since that means I get another chance to do it correctly. But, I'll pass on that opportunity and just ask for the grade.

> Oh no, now I'm on the spot. Well, I'm afraid I have some bad news for you, Hiran: Your code doesn't produce the correct results (except in the case of one row). It is always left-justified. So, we'll have to give you an 'incomplete' for now...

> On another front, while looking at your code, I noticed a problem in the display of the less-than symbol: it gets treated as HTML and the for-loops get all messed up. The problem can be solved by using < to get the "<" symbol to show (even inside the pre blocks). However, now when you look in the message text area below, all is fine. So there is a dichotomy: using the HTML symbols in the code posting will give a nice display, but the code cannot be cut-and-pasted (from the text area) into your favorite editor and easily compiled (you'll have to change the HTML symbols first). Oh well.
