In this post, we will solve Ruby Tutorial – Object Methods HackerRank Solution. This problem (Ruby Tutorial – Object Methods) is a part of HackerRank Ruby series.
Task
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? 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.
Hint
Type in the code-editor
return number.even?or
number.even?Input Format
The first line of input contains an integer n. The next n contains one integer in each line.
Output Format
The output is handled by the code written in the editor.
Solution – Ruby Tutorial – Object Methods Solution
def odd_or_even(number)
