Develop a class diagram for a message class for a cell phone company. include generalizations for child
classes textmessage, videomessage, and voicemessage.

the message class has attributes of account number and price. in addition it has the methods
getinfo(accountnum) and

the subclasses each have one additional attribute of thier own. textmessage has characterlength,
videomessage has messsize and voicemessage has numminutes.

each subclass overrides the methods of the superclass with thier own. no getter or setter methods need to
be documented.

hint: the message class will have a constructor that takes the account number as an argument. each subclass should also have their own constructor which takes their respective additional attribute as an argument; as well as the account number, obviously.

Some of your friends have gotten into the burgeoning field of time-series data mining, in which one looks for patterns in sequences of events that occur over time. purchases at stock exchanges--what’s being bought-- are one source of data with a natural ordering in time. given a long sequence s of such events, your friends want an efficient way to detect certain "patterns" in them--for example, they may want to know if the four events buy yahoo, buy ebay, buy yahoo, buy oracle occur in this sequence s, in order but not necessarily consecutively. they begin with a collection of possible events (e.g., the possible’ transactions) and a sequence s of n of these events. a given event may occur multiple times in s (e.g., yahoo stock may be bought many times in a single sequence s). we will say that a sequence s’ is a subsequence of s if there is a way to delete certain of the events from s so that the remaining events, in order, are equal to the sequence s’. so, for example, the sequence of four events above is a subsequence of the sequence buy amazon, buy yahoo, buy ebay, buy yahoo, buy yahoo, buy oracle their goal is to be able to dream up short sequences and quickly detect whether they are subsequences of s. so this is the problem they pose to you: give an algorithm that takes two sequences of even~s--s’ of length m and s of length n, each possibly containing an event more than once--and decides in time o(m n) whether s’ is a subsequence of s
