##### Canadian Computing Competition: 2019 Stage 1, Junior #4, Senior #1

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.

#### Input Specification

The input consists of one line, composed of a sequence of at least one and at most 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 characters in the input.

#### 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`

#### Sample Output 1

```
4 3
2 1
```

#### Sample Input 2

`VVHH`

#### Sample Output 2

```
1 2
3 4
```

Why is the memory limit so high?

here: https://dmoj.ca/submission/3607125 why i got error It passes on my local ide though

You got Horizontal and Vertical flips mixed up.

2 verticals cancel out

Can anyone tell me how I can fix my whitespace?

ur problem is that ur if conditionals need to reversed. Not a whitespace prblem

Thank you so much
