You're still missing a couple of cases:

function remove(integer n, sequence s)
  integer len
  len = length(s)
  if len>1 then
    if n=1 then
      return s[2..len]
    elsif n=len then
      return s[1..len-1]
    end if
    return s[1..n-1] & s[n+1..len]
  end if
  return {}
end function

That covers it.
