Hidden message in Google Code Jam

I was practicing for this year's google code jam and I found something interesting. The problem I'm talking about is All your base. I'm not going into the details of solving it, but when I took a look at the input cases for the large dataset I found a message telling you clues about the solution of the problem. Here is the input for the large dataset:
At lines 25, 26 and 27 you can read "the left most digit is a one then you count up from there" and from 28 to 34 "do not forget that the results can get very big so be careful go read the large input for year of codejam in the final from last year". For me these are clear clues about solving the problem. Also I found a reference to Portal by stating "but remember the cake is a lie", nice touch.
