How to check if Two Arrays have Same Elements (Regardless of Order) in Rust

How to check if Two Arrays have Same Elements (Regardless of Order) in Rust ?

Answer

To check if two arrays have the same elements regardless of order in Rust, you can sort both arrays and then compare them element by element.

✐ Examples

1 Arrays with Same Elements (Order Ignored)

In this example,

We create two arrays named arr1 and arr2 with the same elements but in different order.
We sort both arrays using the sort method.
We then define a function arrays_equal that checks if the sorted arrays are equal.
Finally, we call arrays_equal to compare the arrays and print the result to the console.

Rust Program

fn arrays_equal(arr1: &mut [i32], arr2: &mut [i32]) -> bool {
    arr1.sort();
    arr2.sort();

    arr1 == arr2
}

fn main() {
    let mut arr1 = [1, 2, 3];
    let mut arr2 = [3, 1, 2];

    let is_equal = arrays_equal(&mut arr1, &mut arr2);
    println!("{}", is_equal);
}

Output

true

2 Arrays with Different Elements (Order Ignored)

In this example,

We create two arrays named arr3 and arr4 with different elements.
We sort both arrays using the sort method.
We then define a function arrays_equal that checks if the sorted arrays are equal.
Finally, we call arrays_equal to compare the arrays and print the result to the console.

Rust Program

fn arrays_equal(arr1: &mut [i32], arr2: &mut [i32]) -> bool {
    arr1.sort();
    arr2.sort();

    arr1 == arr2
}

fn main() {
    let mut arr3 = [1, 2, 3];
    let mut arr4 = [4, 5, 6];

    let is_equal = arrays_equal(&mut arr3, &mut arr4);
    println!("{}", is_equal);
}

Output

false
