How to create a Set of Numbers from 1 to N in Rust


How to create a Set of Numbers from 1 to N in Rust ?

Answer

To create a set of numbers from 1 to N in Rust, you can use a for loop to add elements to a HashSet.



✐ Examples

1 Create a Set of Numbers from 1 to 5

In this example,

  1. We import the std::collections::HashSet module to use HashSet in Rust.
  2. We create an empty HashSet named number_set to store the numbers.
  3. We use a for loop to iterate from 1 to 5 and add each number to the set using the insert method.

Rust Program

use std::collections::HashSet;

fn main() {
    let mut number_set = HashSet::new();
    for i in 1..=5 {
        number_set.insert(i);
    }
    println!("Set of numbers from 1 to 5: {:?}", number_set);
}

Output

Set of numbers from 1 to 5: {1, 2, 3, 4, 5}

2 Create a Set of Numbers from 1 to 10

In this example,

  1. We import the std::collections::HashSet module to use HashSet in Rust.
  2. We create an empty HashSet named number_set to store the numbers.
  3. We use a for loop to iterate from 1 to 10 and add each number to the set using the insert method.

Rust Program

use std::collections::HashSet;

fn main() {
    let mut number_set = HashSet::new();
    for i in 1..=10 {
        number_set.insert(i);
    }
    println!("Set of numbers from 1 to 10: {:?}", number_set);
}

Output

Set of numbers from 1 to 10: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Summary

In this tutorial, we learned How to create a Set of Numbers from 1 to N in Rust language with well detailed examples.
