Question:
Problem 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 Specification
The input consists of one line, composed of a sequence of at least one and at most 1 000 000 characters. Each character is either H, representing a horizontal flip, or V, representing a vertical flip.
Output Specification
Output the final orientation of the four numbers. Specifically, each of the two lines of output will
contain two integers, separated by one space.
Sample Input 1 HV Output for Sample Input 1 4 3 2 1
Sample Input 2 VVHH Output for Sample Input 2 1 2 3 4
