select the first two elements of an array, loop over them such that their index numbers become digits (like 01) in ruby

You can use the slice method to select the first two elements of an array. Then, you can use a loop to iterate over them and convert their index numbers into digits. Here's an example:

main.rb
array = [10, 20, 30, 40, 50] 

# Select the first two elements
selected_elements = array.slice(0, 2)

# Loop over the selected elements
selected_elements.each_with_index do |element, index|
  # Convert the index number into a two-digit string
  digit = format('%02d', index + 1)

  # Print the digit and corresponding element
  puts "Digit: #{digit}, Element: #{element}"
end
376 chars
14 lines

Output:

main.rb
Digit: 01, Element: 10
Digit: 02, Element: 20
46 chars
3 lines

In this example, the slice method is used to select the first two elements of the array. Then, the each_with_index method is used to loop over the selected elements, providing both the element value and its index. The format method is used to convert the index number into a two-digit string, and then the digit and corresponding element are printed inside the loop.
