rectangles: Add newline to the stub template message
So the message is closer to the displayed input lines
pub fn count(lines: &[&str]) -> u32 {
- unimplemented!("Determine the count of rectangles in the ASCII diagram represented by the following lines:\n{:#?}\n.", lines);
+ unimplemented!("\nDetermine the count of rectangles in the ASCII diagram represented by the following lines:\n{:#?}\n.", lines);
}
