Checking if a number is odd or even in Ruby

[Qomplainerz]

Example 1.
Let's see if 1 is even by executing the following code:

puts 1.even?

This will print "false" on the screen, because 1 is not even.

Example 2.
Let's see if 2 is even by executing the following code:

puts 2.even?

This will print "true" on the screen, because 2 is even.

Example 3.
Let's see if 1 is odd by executing the following code:

puts 1.odd?

This will print "true" on the screen, because 1 is odd.

Example 4.
Let's see if 2 is odd by executing the following code:

puts 2.odd?

This will print "false" on the screen, because 2 is not odd.
