Here are a few different ways in which you can split strings in Ruby.
#!/usr/bin/ruby
str = "Hello World! This is how you split strings"
puts str
puts str.split(/ /) # Splits by strings separated by spaces
puts str.split(//) # Split by individual letter
puts str.split(//, 3) # The second parameter determines how many splits are performed
puts str.split("o") # Splits at a letter or string of letters
