Step by Step solution about How to resolve the algorithm Loops/Wrong ranges step by step in the Ruby programming language

The Ruby code provided demonstrates the use of the Range object, which represents a range of values, to create and print sequences of numbers. A detailed explanation of the code is given below:

examples = [
 [-2, 2, 1],
 [-2, 2, 0],
 [-2, 2, -1],
 [-2, 2, 10],
 [2, -2, 1],
 [2, 2, 1],
 [2, 2, -1],
 [2, 2, 0],
 [0, 0, 0],
]

• An array named examples is defined. It contains 9 sub-arrays, where each sub-array represents a set of start, stop, and step values for creating a range.

examples.each do |start, stop, step|
 as = (start..stop).step(step)
 puts "#{as.inspect} size: #{as.size}"
end

• The examples array is iterated over using the each method.
• Inside the loop, for each set of start, stop, and step values:
  • A Range object as is created using the syntax (start..stop).step(step). This creates a range of values from start to stop, incrementing by step.
  • The inspect method is called on as to display the range as a string.
  • The size method is called on as to determine the number of elements in the range.
  • The string representation of the range and its size are printed using puts.

The output generated by the code will vary depending on the input examples. For instance, with the provided examples, the output might look like:

[-2, 0, 2] size: 3
[-2, 2] size: 5
[-2, 4] size: 7
[-2, 12] size: 15
[2, -1, 1] size: 4
[2, 0, 1] size: 3
[2, 4] size: 7
[2, 2] size: 5
[0, 0, 0] size: 1

examples = [
     [ -2,    2,    1],
     [ -2,    2,    0], 
     [ -2,    2,   -1],
     [ -2,    2,   10], 
     [  2,   -2,    1], 
     [  2,    2,    1], 
     [  2,    2,   -1], 
     [  2,    2,    0], 
     [  0,    0,    0]
     ]

examples.each do |start, stop, step|
  as = (start..stop).step(step)
  puts "#{as.inspect} size: #{as.size}"
end
