I believe we have different interpretations of the mechanics of this problem.This wasn't my understanding. I assumed that the first Ctrl+V replaces the three typed A's since they're still selected, much like everyday word-processing software. In otherwords:Spoiler for Some remarks
- Ctrl+A selects
- Ctrl+C copies
- The three A's are still selected
- Ctrl+V replaces the selected A's with pasted ones.
That was the basis for my work, though your interpretation may well be correct. Maybe BMAD could clarify exactly how the process works?
Edit: From BMAD's examples it looks to be the case that the typed A's are indeed replaced. However, your interpretation would make an equally interesting puzzle!
You are right. I solved another puzzle
