Your Private Foursomeby in Bring Your Own Code on 2017-05-17
Last week, I shared some code that, while imperfect, wasn’t that bad. I then issued a challenge: make it worse. Or better, if you really want. As many comments noted: one case covers only the first iteration of the loop, and one case only covers the last iteration of the loop. You could easily pull those out of the loop, and not need a for-case at all. Others noticed that this pattern looked like odd slices out of an identity matrix.
With that in mind, we got a few
MatrixUtils based solutions generally were the “best” solutions to the problem: generate an identity matrix and take slices out of it. This is reasonable and fine. It makes perfect sense. Let’s see if we can avoid making sense.
