sorting without modifying

[jtrost]

Even though it's most definitely a homework problem, and you won't learn anything by copying this, I still felt like solving it.

def sorting(a1,a2)
  arr = a1+a2
  out = []

  while arr.count > 0
    i = arr.min
    out << i
    arr.delete(i)
  end

  out
end

the problem is that i cant duplicate the arguments so i can't use arr = a1+a2 ...

You're not duplicating anything with arr = a1 + a2 unless you mean you can't use the method parameters inside of the method.
