help please

Question

Fill in the blanks to create a method that takes optional parameters and outputs the squares of its parameters:
def sq(

p)

.each {|

| puts x*x}
end

Answer 1

Is this a homework, a question from Ruby challenges, or a logic you're working on?

Anyways, I can think of 2 approaches:

■ Number 1:
def sq(*p)
p.each {|x| puts x*x}
end

■ Number 2:
def sq(*p)
p.each do |x|
puts x*x
end
end
