How to Use Nested Paths (use std

Use curly braces to group multiple items from the same parent module in a single use statement. This syntax imports io and fs from the std crate simultaneously.

use std::{io, fs};

This allows you to call functions like io::stdin() and fs::read_to_string() directly without repeating std::.

Nested paths let you import multiple tools from the same toolbox in one go. Instead of writing the full path for every item, you group them together. It keeps your code cleaner and easier to read.
