Comment Formatter

Given a list of comments with nested replies, write a program to format and print the comments with appropriate indentation. Each comment is represented by an integer id, a user name, and a text message. For each comment, print a line in the format: \(id\ (user):\ text\). Replies to a comment should be indented by two spaces per level.

The input is provided recursively. The first line contains an integer representing the number of top-level comments. For each comment, the following lines are provided in order:

• An integer representing the id.
• A string representing the user (one line).
• A string representing the text message (may contain spaces).
• An integer representing the number of replies.

This structure repeats recursively for each reply.

inputFormat

The input is read from stdin and follows this format:

1. The first line contains an integer \(N\) denoting the number of top-level comments.
2. For each comment, four components are provided in the following order:
• An integer \(id\).
• A line containing the \(user\) name.
• A line containing the \(text\) message.
• An integer \(R\) denoting the number of replies.
3. This structure repeats recursively for each reply.

outputFormat

Output the formatted comments to stdout. Each comment should be printed on its own line in the format:

id (user): text

For replies, indent the line by two spaces for each level of nesting.
