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


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

Answer

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.



✐ Examples

1 Create Set of Numbers from 1 to 5

In this example,

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

Ruby Program

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

Output

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

2 Create Set of Numbers from 1 to 10

In this example,

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

Ruby Program

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

Output

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