We can do this .In ruby The ‘+’ is method.You are calling ‘+’ method
three times.But I have asked using single function we have to do.

I expect that was what the OP was looking for. But on the other hand,
your solution involves two methods, not one. One way to do it with one
method is the following:

require ‘pp’

class Array
def concat_multi! *lists
lists.each {|list| self.concat(list) }
end
end

a = [1, 2, 3]
b = [4, 5, 6]
c = [7, 8, 9]
d = [10, 11]

a.concat_multi!(b, c, d)

pp a

Why? Is this a quiz question? Please explain why it matters that
it’s a single method call.

Does this work for you?:
[a, b, c].flatten
