You're very close - it's simply a = gets.chomp.split (without the
square brackets). I recommend splitting on " " explicitly rather than
relying on it being the default.

a = gets.chomp.split(" ")

Note that what you did was create an array containing the return value
of gets.chomp.split:

input = "hello world"
a = input.split #=> ["hello", "world"]
a = [input.split] #=> [["hello", "world"]]

in the latter case, you get an array of length 1, whose only element
is an array of length 2.
