rust reverse for loop
To write a reverse loop in Rust, you can use the rev
method provided by the Iterator
trait. Here's an example:
fn main() {
let numbers = vec![1, 2, 3, 4, 5];
for number in numbers.iter().rev() {
println!("{}", number);
}
}
In this example, we have a vector numbers
containing the values [1, 2, 3, 4, 5]
. By calling iter().rev()
on the vector, we create an iterator that produces the elements in reverse order. The for
loop then iterates over each element in reverse and prints it.
I hope this helps! Let me know if you have any further questions.
