Matrix Rotations

You are given a square matrix A of dimensions NxN. You need to apply the below given 3 operations on the matrix A.

Rotation: It is represented as R S where S is an integer in {90, 180, 270, 360, 450, ...} which denotes the number of degrees to rotate. You need to rotate the matrix A by angle S in the clockwise direction. The angle of rotation(S) will always be in multiples of 90 degrees.

Update: It is represented as U X Y Z. In initial matrix A (as given in input), you need to update the element at row index X and column index Y with value Z.

After the update, all the previous rotation operations have to be applied to the updated initial matrix.

Querying: It is represented as Q K L. You need to print the value at row index K and column index L of the matrix A.

Input

The first line contains a single integer N.

Next N lines contain N space-separated integers Aij (i - index of the row, j - index of the column).

Next lines contain various operations on the array. Each operation on each line (Beginning either with R, U or Q).

-1 will represent the end of input.

Output

For each Query operation print the element present at row index K and colum index L of the matrix in its current state.

For R 90, clockwise rotation by 90 degrees, the matrix will become

4 2

For Q 0 0, print the element at row index 0 and column index 0 of A, which is 3.

For Q 0 1, print the element at row index 0 and column index 1 of A, which is 1.

Again for R 90, clockwise rotation by 90 degrees, the matrix will become

4 3

2 1

For Q 0 0, print the element at row index 0 and column index 0 of A, which is 4.

For U 0 0 6, update the value at row index 0 and column index 1 in the initial matrix to 6. So the updated matrix will be,

6 2

3 4

After updating, we need to rotate the matrix by sum of all rotation angles applied till now(i.e. R 90 and R 90 => 90 + 90 => 180 degrees in clockwise direction).

After rotation the matrix will now become

4 3

Next for Q 1 1, print the element at row index 1 and column index 1 of A, which is 6.

Use a canvas of any reasonable size. Across the top of the canvas are 3 stationary lightbulbs (circles).

• If a lightbulb is currently turned on, it should be colored yellow. If it’s currently turned on, it should be colored black. When your program first starts, have 1 bulb on and the other 2 off.

• When the user clicks a lightbulb: Turn that lightbulb on (if it was off) or off (if it was on).

• The background color should depend on how many lightbulbs are currently turned on. If all of them are on, it should be white. If all of them are off, it should be black. If one of them is on, it should be dark grey. If two of them are on, it should be light grey

A queue is observed over 10000 one-second time intervals with data as given below in the array qdata.

Construct a Poisson nearest neighbour model with a single arrival and servicing pattern and hence answer the following questions:

1. What is the average time taken for 1 customer to arrive?
2. What is the average number of customer servicings per second?
3. What is your estimate for the equilibrium probability 𝑃(𝑛≥4)
4. P(n≥4), where 𝑛
5. n is the queue size in this model?
6. Suppose that two equivalent servers are introduced. What would the equilibrium probability 𝑃(𝑛≥4)
7. P(n≥4) then be?

Matrix Rotations

You are given a square matrix A of dimensions NxN. You need to apply the below given 3 operations on the matrix A.

Rotation: It is represented as R S where S is an integer in {90, 180, 270, 360, 450, ...} which denotes the number of degrees to rotate. You need to rotate the matrix A by angle S in the clockwise direction. The angle of rotation(S) will always be in multiples of 90 degrees.

Update: It is represented as U X Y Z. In initial matrix A (as given in input), you need to update the element at row index X and column index Y with value Z.

After the update, all the previous rotation operations have to be applied to the updated initial matrix.

Querying: It is represented as Q K L. You need to print the value at row index K and column index L of the matrix A.

Input

The first line contains a single integer N.

Next N lines contain N space-separated integers Aij (i - index of the row, j - index of the column).

Next lines contain various operations on the array. Each operation on each line (Beginning either with R, U or Q).

-1 will represent the end of input.

Output

For each Query operation print the element present at row index K and column index L of the matrix in its current state.

Tic-Tac-Toe game

Abhinav and Anjali are playing the Tic-Tac-Toe game. Tic-Tac-Toe is a game played on a grid that's three squares by three squares. Abhinav is O, and Anjali is X. Players take turns putting their marks in empty squares. The first player to get 3 of her marks in a diagonal or horizontal, or vertical row is the winner. When all nine squares are complete, the game is over. If no player has three marks in a row, the game ends in a tie. Write a program to decide the winner in the Tic-Tac-Toe game.

Input

The input will be three lines contain O's and X's separated by space.

Output

The output should be a single line containing either "Abhinav Wins" or "Anjali Wins" or "Tie".

Explanation

For example, if the input is

O X O
O X X
O O X 

as three of O's are in vertical row print "Abhinav Wins".

Sample Input 1

O X O
