How to create a Set of Numbers from 1 to N in Ruby - Step by Step Examples

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

To create a set of numbers from 1 to N in Ruby, you can use a Hash or Set data structure where the keys or elements represent the numbers.

In this example,

We require the 'set' library to use the Set data structure.
We initialize an empty Set named number_set.
We use a for loop to iterate from 1 to 5 (inclusive).
Inside the loop, we add each number to the set using the add method of the Set object.
The resulting set contains numbers from 1 to 5.

require 'set'

number_set = Set.new

(1..5).each do |i|
  number_set.add(i)
end

puts 'Set of numbers from 1 to 5:', number_set.inspect

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

In this example,

We require the 'set' library to use the Set data structure.
We initialize an empty Set named number_set.
We use a for loop to iterate from 1 to 10 (inclusive).
Inside the loop, we add each number to the set using the add method of the Set object.
The resulting set contains numbers from 1 to 10.

require 'set'

number_set = Set.new

(1..10).each do |i|
  number_set.add(i)
end

puts 'Set of numbers from 1 to 10:', number_set.inspect

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

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