rust iterate vector backwards
To iterate over a vector in Rust backwards, you can use the iter
method in conjunction with the rev
method. Here's an example:
fn main() {
let vector = vec![1, 2, 3, 4, 5];
for element in vector.iter().rev() {
println!("{}", element);
}
}
In this example, the iter
method is used to create an iterator over the vector, and the rev
method is called on the iterator to reverse its order. The resulting iterator is then used in the for
loop to iterate over the vector elements in reverse order.
