Machine Command Translator

You are given a series of commands, each consisting of two words: an action and a direction.

The available actions and their corresponding abbreviations are given by:

\( \text{walk}\to W,\quad \text{run}\to R,\quad \text{jump}\to J,\quad \text{stop}\to S \)

The available directions and their abbreviations are:

\( \text{left}\to L,\quad \text{right}\to R,\quad \text{forward}\to F,\quad \text{backward}\to B \)

For each command in the input, output the machine instruction which is the concatenation of the corresponding abbreviations. For a command with action \(a\) and direction \(d\), the output will be:

\( \text{output} = \text{action_mapping}[a] + \text{direction_mapping}[d] \)

If there are no commands, output nothing.

inputFormat

The first line contains an integer \( n \) representing the number of commands.

The following \( n \) lines each contain a command consisting of two words separated by a space.

Input is provided via standard input (stdin).

outputFormat

Output \( n \) lines where each line is the machine instruction corresponding to the input command. Output is printed to standard output (stdout).
