Have you looked at the documentation and help files for R Import/Export;
http://cran.r-project.org/doc/manuals/R-data.pdf
and the read functions
?read.table
?readLines
?count.fields
This is pretty basic stuff. After an extremely cursory look at that
problem I was guessing that it is more like linear programming than
statistics.

Dear R buddies,
This weekend I became interested in solving Google Code Jam problems
using R. I guess R may work very well in this kind of contests but the
input of file has been a problem for me. Take this case for example
(http://code.google.com/codejam/contest/dashboard?c=agdjb2RlamFtchALEghjb250ZXN0cxjRzBQM
),
the files are usually of the form:
A(number of lines for group 1)
a11 a12 a13
a21 a22 a23
...
B(number of lines for group 2)
b11 b12 b13
b21 b22 b23
...
I guess SAS may work pretty well in this kind of situation with data
step. But I don't know how to handle them using R. Any suggestions?
Thanks a lot.
Best wishes,
