Description

Create a class Matrix to represent an N * N matrix.

 

Provide public member functions that perform or derive:

     1) Matrix(const Matrix &);  // copy constructor

 

     2) Overload the stream extraction operator (>>) to read in the matrix elements.

 

    3)  Overload the stream insertion operator (<<) to print the content of the matrix row by row.

 

     4)  Default constructor

 

    5)  Overload the operator (=) to assign value to matrix.

         Note that all of the integers in the same line are separated by a space, and there is a new line character at the end of each line.

 

Note:

1.  This problem involves three files.

• function.h: Class definition of Matrix.
• function.cpp: Member-function definitions of Matrix.
• main.cpp: A driver program to test your class implementation.

You will be provided with function.h and main.cpp, and asked to implement 

 

2. For OJ submission:

       Step 1. Include function.h into function.cpp and then implement your function.cpp. (You don’t need to modify function.h and main.cpp)

       Step 2. Submit the code of function.cpp into submission block.

       Step 3. Check the results and debug your program if necessary.

Input

The first line has an integer N (1<=N<=50), which means the size of the matrix. The total number of elements in the matrix is thus N * N.

 

For the next N lines specify the elements of the matrix a. All of the integers in the same line are separated by a space.

Output

Your program should print the corresponding results followed by a new line character.

Description

After watching the movie 21, Kuo is curious about casino.

 

There is a casino which opens N days in this month.

There will be two kind of events in a day.

1. Guest <Someone> <Money> <Skill>. It means <Someone> enter the casino with <Money> money. <Someone> are their names, <Money> is the amount of money with them, and <Skill> is how well they play. If <Someone> are already in the casino or are blacklisted, ignore this event.
2. Win <Someone> <Money>. It means <Someone> win <Money> money in a play from the casino. <Money> may be positive or negative. If <Someone> are not in the casino or are blacklisted, ignore this event.

 

Whenever one become bankrupt, they will be kicked out of the casino and be blacklisted.

If the amout of money someone win in a play exceed (that is, >) twice of their <Skill>, they will be seen as cheaters, kicked out of the casino, and blacklisted. (The casino still has to pay the money they win to them.)

Someone blacklisted are not permitted to enter the casino.

Note: If someone have to pay X money but they only have Y money where Y <= X, they will only pay Y money and become bankrupt.

At the end of each day, everyone will leave the casino.

 

Please help Kuo-chan find how much income the casino gets in this month and who are blacklisted.

Input

The first line of the input contains a number N — the number of days in this month.

The following contains N blocks.

The first line of each block is Casino Q — it means there will be Q events this day.

The next Q lines is one of the following:

1. Guest <Someone> <Money> <Skill>
2. Win <Someone> <Money>

 

N <= 1000, Q <= 100. 

There will be at most 1000 different people come to the casino; that is, there are at most 1000 people with different names. Therefore, there will be at most 1000 people blacklisted.

All number is within the range of int.

Output

You should print a number U in the first line — how much income the casino gets in this month.

If there are K people blacklisted in this month, you should output their names in K lines in the order they get blacklisted.
