9370: CCC '19 J4/S1 - Flipper
Description
You are trying to pass the time while at the optometrist. You notice there is a grid of four numbers:
1 | 2 |
3 | 4 |
You see lots of mirrors and lenses at the optometrist, and wonder how flipping the grid horizontally or vertically would change the grid.
Specifically, a "horizontal" flip (across the horizontal centre line) would take the original grid of four numbers and result in:
3 | 4 |
1 | 2 |
A "vertical" flip (across the vertical centre line) would take the original grid of four numbers and result in:
2 | 1 |
4 | 3 |
Your task is to determine the final orientation of the numbers in the grid after a sequence of horizontal and vertical flips.
Input
