Create a class called MathTest Outside of the class, import the Scanner library Create a method called main Inside main: 1. Declare two integer variables and two double variables 2. Instantiate a Scanner object 3. Using print, display two lines that allows the user to enter in the two integer values on the same line as the prompt. 4. Using print, display two lines that allows the user to enter in the two double values on the same line as the prompt. 5. Using multiple printf statements, display the result of adding, subtracting, multiplying, dividing and moding the two integer values. 6. Using multiple printf statements, display the result of adding, subtracting, multiplying, and dividing the two double values. 7. Make sure that there is a title before each of the two outputs and there are blank lines between the input section and the two output sections. 8. Comment your code.

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

A911 dispatcher is the sole sender of messages to all police officers. while on patrol, officers communicate with the dispatcher who, in turn, relays messages to other officers. the officers do not communicate directly with one another. this illustrates a network.

The forerunner to cell phones, pdas, and smartphones was
