Sentence Modifier Commands

You are given a sentence and a list of commands. Each command instructs you to modify the sentence in a particular way. The commands are applied sequentially. There are three types of commands:

• Upper n: Convert the first n words of the sentence to uppercase.
• Lower n: Convert the last n words of the sentence to lowercase.
• Reverse n: Reverse the order of the first n words.

If there are fewer than n words in the sentence for a given command, apply the command to all available words. If no commands are provided, output the sentence unchanged.

Note: All modifications are applied in the order in which the commands are given.

inputFormat

The input is read from standard input (stdin) and has the following format:

<sentence>
<number_of_commands>
<command1>
<command2>
...
<commandN>

Here, the first line is the sentence (words separated by spaces), the second line is an integer specifying the number of commands, followed by that many lines each containing a command.

outputFormat

Output the modified sentence using standard output (stdout) after all commands have been applied.
