Data: we wish to allow our string class to accommodate strings of different sizes. to that end, instead of storing a string’s characters in a fixed-size array, each string object should contain the following data as part of its internal representation: (1) a character pointer meant to point to a dynamically-allocated array of characters. (2) a length field that will hold the current length of the string at any given moment. operations: same as the methods in string class, plus the "big three"( destructor, copy constructor, and assignment operator overloading). modularity: the string class code must be put in its own module, i. e., a file mystring2.h (the header file) should hold the class definition (use conditional compilation directives) and a file mystring2.cpp (the implementation file) should hold the method definitions.

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
