Re:[OT] Trivial Q

[David Derry <dd...@acm.org>]

This will work some of the time (maybe most). But you are missing edge
conditions. take 8 for ex. in a 4X4 that would be row 2 column 4. But your
foumula places it at row 3 column 0. However, right now I can't think of a
better solution (too early on a Mon morning!), other than to test for column
== 0, in which case --row; column = numberOfColumns.
