Tic Tac Toe程序。可以供一到兩個玩家使用。程序中使用了visual basic 計時器，所以每一個步驟都有時間限制。此外，計算機可是一個有簡單智能的對手，他不但不會隨便出手，反而還要竭力贏了你才罷休。
Tic Tac Toe program. One or two players. It uses the visual basic timer, so each move has time limit. Simple artificial intelligence: computer does not play randomly, but "tries" to win and stop you from winning.
The cart with an inverted pendulum, shown below, is "bumped" with an impulse
force, F. Determine the dynamic equations of motion for the system, and lin
earize about the pendulum s angle, theta = Pi (in other words, assume that p
endulum does not move more than a few degrees away from the vertical, chosen
to be at an angle of Pi). Find a controller to satisfy all of the design re
quirements given below.
In most software-development organizations, the testing program functions as the
final "quality gate" for an application, allowing or preventing the move from the
comfort of the software-engineering environment into the real world. With this role
comes a large responsibility: The success of an application, and possibly of theorganization, can rest on the quality of the software product.

A weird clock marked from 0 to 59 has only a minute hand. It won t move until a special coin is thrown into its box. There are different kinds of coins as your options. However once you make your choice, you cannot use any other kind. There are infinite number of coins of each kind, each marked with a number d ( 0 <= 1000 ), meaning that this coin will make the minute hand move d times clockwise the current time. For example, if the current time is 45, and d = 2. Then the minute hand will move clockwise 90 minutes and will be pointing to 15.
Now you are given the initial time s ( 0 <= s <= 59 ) and the coin s type d. Write a program to find the minimum number of d-coins needed to turn the minute hand back to 0.

the hardware for the game includes a number of displays, each with a button and
-- a light, that each represent a bin that can store marbles (beans).
--
-- The display indicates the number of marbles in each bin at any given time.
-- The light indecates that the present bin is not empty and that pushing the
-- button is a valid move in the game.
--
-- The button for each display indicates that a player takes the marbles from
-- the selected bin, and takes them in his hand. The hand is represented by a
-- diplay itself (no button).
--
-- Each player has a home bin, located on opposite sides of the game.

The goal of this library is to make ODBC recordsets look just like an STL container. As a user, you can move through our containers using standard STL iterators and if you insert(), erase() or replace() records in our containers changes can be automatically committed to the database for you. The library s compliance with the STL iterator and container standards means you can plug our abstractions into a wide variety of STL algorithms for data storage, searching and manipulation. In addition, the C++ reflection mechanism used by our library to bind to database tables allows us to add generic indexing and lookup properties to our containers with no special code required from the end-user. Because our code takes full advantage of the template mechanism, it adds minimal overhead compared with using raw ODBC calls to access a database.

input:The input consists of T test cases. The number of test cases ) (T is given in the first line of the input. Each test case begins with a line containing an integer N , 1<=N<=200 , that represents the number of tables to move. Each of the following N lines contains two positive integers s and t, representing that a table is to move from room number s to room number t (each room number appears at most once in the N lines). From the N+3-rd line, the remaining test cases are listed in the same manner as above.
