**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

**, representing a vertical flip.**

*V***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
