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.
