7) If you will have less than 9 parameters, you can do this:

param_str = temp = 'x1'

10.times do |i|
  temp = temp.succ
  param_str << ', ' << temp
end

p param_str

--output:--
"x1, x2, x3, x4, x5, x6, x7, x8, x9, y0, y1"

But in ruby, you can define variadic methods:

def my_meth(*args)
  args.each {|arg| p arg}
end

my_meth(1, 2, 3)
my_meth('a', 'b', 4)

--output:--
1
2
3
"a"
"b"
4
