[RUBY] [Rails] Get standard input for multi-line data

Personal notes.

Store multiple lines of data in an array with standard input

value = readlines.map(&:chomp)

If there are multiple data in one row with standard input, store them in an array

Example) Apple banana

line = gets.split
p line

Output multiple data stored in an array to one line

There is a space between data, you can specify a specific symbol etc. ・ If blank

puts array.join(' ')
Apple banana

·#in the case of

puts array.join('#')
