It’s been a while since Irreal has had an EmacsGolf challenge but yesterday’s post on Programming Silliness suggested a nice one. When I ran the grep, I got
| A |
| a |
| aa |
| Ab |
| aba |
| … |
| faff |
| fe |
| fed |
| fee |
| feed |
The challenge is in two parts:
- Rearrange the long, single column list into four columns the way it was in yesterday’s post.
- I was lazy in yesterday’s post and left the results sorted by rows instead of the more natural by columns. Rearrange the list so that the results are sorted by columns.
