Description

In this problem, you are asked to implement a program which can find the maximum element M and minimum element mof a two-dimensional array. You need to print the location difference and value difference of M and m. For example, if M is at iM-th row and jM-th column and of value rM, and m is at im-th row and jm-th column and of value rm, then the location difference and value difference of the two elements are (|iM - im| + |jM - jm|) and (|rM - rm|), respectively.

Note that in a given array, no two elements will have the same value.

 

HINT: You can use C library function:  int abs(int x) ,which returns the absolute value of int x.

Before using abs(), you may need to add the following code at first : #include <stdlib.h>

Input

The first line of the input contains two integer numbers R (2<=R<=10) and C (2<=C<=10).

Each of the next R lines contains C integers, specifying the elements of the two-dimensional array. All of the integers in the same line are separated by a space.

Output

The output contains two integers:  the location difference and the value difference of the maximum and minimum elements, separated by a space.

Note that you do not need to print ‘\n’ at the end of line.

Description

There are N players in a trading card game(集換式卡牌遊戲), each player has a card binder that holds a certain number of cards. Player i 's binder has Mi card slots, and initially, the j-th slot of player i 's binder holds a unique card numbered A_{i, j}.

Since this is a trading card game, "card trading" is naturally an essential aspect. You are given T trades between the players. Each trade involves 4 numbers: x1_i , y1_i , x2_i , and y2_i . This means player x1_i trades the card in slot y1_i of their binder with the card in slot y2_i of player x2_i ’s binder.

The trades occur in the order they are given. That is, the i-th trade happens before the (i +1)-th trade.

After all the trades are completed, you need to answer Q queries. Each query consists of a number, num_i. For each query, you need to report two numbers, p_i and c_i, representing that the card numbered num_i is in slot c_i of player p_i's binder after all the trades have taken place.

Input

The first line of input contains an integer N, representing the number of players.

The second line contains N integers M₁, M₂, ..., M_N, where M_i represents the capacity (number of cards) of the i-th player's card binder.

The next N lines, where the i-th line contains M_i integers, represent the initial card numbers in the binder of the i-th player: A_{i, 1}, A_{i, 2}, ..., A_{i, Mi}.

After that, there is an integer T representing the number of card trades.

The next T lines each contain 4 integers x1_i, y1_i, x2_i, y2_i, indicating that the card in the y1_i -th slot of the x1_i -th player’s binder is traded with the card in the y2_i -th slot of the x2_i -th player’s binder.

The final line contains an integer Q, representing the number of queries.

The next line contains Q integers num₁, num₂, ..., num_Q , separated by spaces, representing queries asking for the locations of the cards numbered num_i.

Subtasks

• Testcases 1: N = 1 ; T = 0
• Testcases 2~4: N = 1 ; T,Q ≤ 100 
• Testcases 5~6: N = 1
• Testcases 7: N = 2 ; Q ≤ 100
• Testcases 8: N,Q ≤ 100
• Testcases 9~10: No additional restrictions.

Output

For each query, output two integers, p_i and c_i representing that the card numbered num_i is in the c_i-th slot of the p_i-th player's binder after all the trades have taken place.

Please remember to print "\n" at the end of each query.

When outputting p_i and c_i, ensure there is a space between them, and make sure there is no space after c_i. Otherwise, you may get a Presentation Error.
