Step by Step solution about How to resolve the algorithm Pick random element step by step in the Ruby programming language

The provided Ruby code utilizes the sample method to randomly select one or more elements from a collection of values. Here's a breakdown of what the code does:

1. %w(north east south west).sample: Creates an array containing the strings "north," "east," "south," and "west," and then uses the sample method to randomly select one string from the array. The sample method is part of Ruby's Enumerable module, which provides various methods for working with collections of objects.

2. (1..100).to_a.sample(2): Creates a range of integers from 1 to 100, converts it to an array using the to_a method, and then uses the sample method with the argument 2 to randomly select two integers from the array. The result will be an array containing two randomly selected integers between 1 and 100.

In summary, the code generates a random selection from a list of strings and a random selection from a range of integers. The sample method is a useful tool for selecting random elements from a collection of objects, making it a versatile function for various applications in Ruby programming.

%w(north east south west).sample   # => "west"
(1..100).to_a.sample(2)            # => [17, 79]
