How to Reverse a Vector in Rust ?

Answer

To reverse a vector in Rust, you can use the `reverse` method.

✐ Examples

1 Reverse a Vector of Integers

In this example,

We create a vector named int_vector containing integers.
We use the reverse method to reverse the order of elements in the vector.

Rust Program

let mut int_vector = vec![1, 2, 3, 4, 5];
int_vector.reverse();
println!("{:?}", int_vector);

Output

[5, 4, 3, 2, 1]

2 Reverse a Vector of Characters

In this example,

We create a vector named char_vector containing characters.
We use the reverse method to reverse the order of elements in the vector.

Rust Program

let mut char_vector = vec!["a", "b", "c", "d", "e"];
char_vector.reverse();
println!("{:?}", char_vector);

Output

["e", "d", "c", "b", "a"]
