"Add a remove method to remove a security from the portfolio and return the removed object pair as a 2-tuple. If the security is not in the portfolio, return the symbol and -1 as a 2-tuple. Hint: Use either the ""-"" operator or the ""-="" operator."

our.remove("JNJ") // (String, Int) = (JNJ,25) our.remove("JNJ") // (String, Int) = (JNJ,-1)

Our in this case would just be an instance of the portfolio class.
