Comparing numbers from ready-made variables and an array consisting of a range?

Question

ruby

There are condition variables:

a = [1, 2]
b = [3, 4]
c = [5 ,6]

And the array from the range: There is an extra number - 7 I need to compare the numbers from the variables with an array of numbers and identify matches and mismatches. How to do?

abc = (1..7).to_a

Answer 1

a = [1, 2]
b = [3, 4]
c = [5 ,6]

abc = (1..7).to_a

abc.each { |num| (a+b+c).include?(num) ? (puts "#{num} is include in variables") : (puts "#{num} is not include in variables")}
