Struct year2015::Day06

pub struct Day06 { /* private fields */ }

2015 Day 6: Light grid.

Reducing the 1000x1000 grid based on the unique x and y bounds in the input gives a ~4x speedup. For example, the 1000x1000 grid for this input:

turn on 0,0 through 999,999
toggle 0,0 through 999,0
turn off 499,499 through 500,500

Can be converted into this 3x4 grid:

| 0,0   through 498,0   | 499,0   through 500,0   | 501,0   through 999,0   |
| 0,1   through 498,498 | 499,1   through 500,498 | 501,1   through 999,498 |
| 0,499 through 498,500 | 499,499 through 500,500 | 501,499 through 999,500 |
| 0,501 through 498,999 | 499,501 through 500,999 | 501,501 through 999,999 |
