How to find a subset of set1 and set2 in Ruby using < operator
okwudili onyejiaku
Overview
In Ruby, we use the less-than operator < to determine if a particular set is a subset of another. If set1 is a subset of set2, then all the elements of set1 are present in set2. Remember that a set is a collection of unordered values without duplicates.
Syntax
set1 < set2
Syntax to check if a set is a subset of another in Ruby
Parameters
set1: This is the set for which we want to check if it is the subset of set2.
set2: This is the set for which we want to check if set1 is its subset.
Return value
A Boolean value is returned, which tells that set1 is a subset of sub2. If it is a subset then a true is returned, otherwise false.
Example
# require set require "set" # create some sets EvenNumbers = Set.new([2, 4, 6, 8, 10]) NumbersToTen = Set.new([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]) Names = Set.new(["Amaka", "Titi"]) Workers = Set.new(["Amaka", "Chioma", "Titi"]) # get the intersection puts EvenNumbers < NumbersToTen # true puts Workers < Names # false
Check if a set is a subset of another in Ruby
Explanation
- Line 2: We use
requireto get the set class. - Line 5–8: We create some new sets and initialize them with some values.
- Line 11–12: We use the
<operator to check if some sets were subsets for another.
