aoc10: 80x80 canvas?

[Dominic Evans]

I was wondering how you determined from the instructions that the points would all fit within an 80x80 canvas when the message was being displayed?

advent-of-code/aoc10/src/main.rs

Lines 29 to 37 in 6285296

 for _ in 0..1_000_000 { 
     points.step(); 
     let (w, h) = points.dimensions(); 
     if w <= 80 && h <= 80 { 
         writeln!(io::stdout(), "seconds: {}", points.seconds)?; 
         writeln!(io::stdout(), "{}", points.grid_string().trim())?; 
         writeln!(io::stdout(), "{}", "~".repeat(79))?; 
     } 
 }
