Rust program to find the Symmetric difference between two HashSets

Rust | HashSet Example: Write a program to find the Symmetric difference between two HashSets.
Last Updated : October 26, 2021

Problem Statement

In this program, we will create two HashSets to store integer items, and then we will find the Symmetric difference between both sets and print the result.

Program/Source Code

The source code to find the Symmetric difference between two HashSets is given below. The given program is compiled and executed successfully.

// Rust program to find the Symmetric 
// difference between two HashSets

use std::collections::HashSet;

fn main() {
    let set1: HashSet<_> = [10, 15, 30, 20,12].iter().cloned().collect();
    let set2: HashSet<_> = [10, 15, 20,40].iter().cloned().collect();

    println!("Symmetric Difference:");
    for diff in set1.symmetric_difference(&set2) {
        print!("{} ", diff); 
    }
}

Output

Symmetric Difference:
12 30 40

Explanation

Here, we created two HashSets to store integer elements. Then we found the symmetric difference between both sets using the symmetric_difference() method. After that, we printed the result.
