Loops in Rust: The Power of `for`

Level: intro (score: 1)

In this exercise, you'll implement a function to compute the sum of numbers within a given range using Rust's for loop.

Task

Implement the function: sum_numbers(start: u32, end: u32) -> u32

- Use a for loop over an inclusive range (start..=end) to compute the sum.
- If start is greater than end, return 0.
- Think of iterating over a fixed set of items, much like processing daily sales records from a known date range.

Hints

• Use start..=end to create an inclusive range.
• Check if start > end before looping (imagine this function as a counter adding up sales revenue between two given dates. If the range is invalid (start > end), no sales are counted).

Happy coding! 🚀
