You are trying to pass the time while at the optometrist. You notice
there is a grid of four numbers:

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:

A “vertical” flip (across the vertical centre line) would take the
original grid of four numbers and result in:

Your task is to determine the final orientation of the numbers in the
grid after a sequence of horizontal and vertical flips.

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.

For 8 of the 15 available marks, there will be at most 1 000
characters in the input.

Output the final orientation of the four numbers. Specifically, each of
the two lines of output will contain two integers, separated by one
space.
