Step by Step solution about How to resolve the algorithm Permutations step by step in the Ruby programming language

This Ruby code demonstrates the use of the permutation method to find all possible permutations of a given array. Let's break down the code step by step:

1. [1,2,3]: This is an array containing the elements 1, 2, and 3.

2. .permutation: The permutation method is called on the array. This method generates all possible permutations of the elements in the array. In this case, it will generate all possible arrangements of the numbers 1, 2, and 3.

3. .to_a: The to_a method converts the result of the permutation method, which is an enumerator, into an array. This makes it easier to work with the results.

4. p: The p method is used to print the results to the console.

When you run this code, you will see the following output:

[[1, 2, 3], [1, 3, 2], [2, 1, 3], [2, 3, 1], [3, 1, 2], [3, 2, 1]]

This shows that the permutation method has generated all six possible permutations of the numbers 1, 2, and 3.
