In this **HackerRank Ruby Tutorial – Object Methods problem solution** Each object in Ruby may have methods associated with it. To demonstrate this, we want you to print whether a number is even or odd. A number has an even? the method associated with it, which returns true or false based on the parity of the number.

Assuming a variable number is already defined, check whether a given number is even or not.

**Input Format**

The first line of input contains an integer n. The next n contains one integer in each line.

## Problem solution.

def odd_or_even(number) return number.even? end (0...gets.to_i).each do |i| puts odd_or_even(gets.to_i) end

Here above is the video that will show you the solution
