Question

My approach

• get array elements as string with delimiter such as space or comma
• split the string
• Convert each element into number and push into the array

The code looks like this:

puts 'Enter array elements with a space'
array_as_string = gets 
if array_as_string.length > 0
  input_array = []
  array_as_string.split(' ').each { |x| input_array.push(x.to_i) }
else
  puts 'Invalid input'
end

Is there a better/ efficient alternative or a straight forward way of doing this?

Answer 1

The default argument for split is whitespace.
The idiom to do
something with every element in an array and get an array as result
is map.

puts "Enter array elements with a space"
array_as_string = gets
array = array_as_string.split.map(&:to_i)
