Ivo has an table. The table has the integers through inscribed in row-major order. The following operations can be done on the table:
- Rotate a row – all cells in a single row are rotated right, so that the number in the last column moves to the first.
- Rotate a column – all cells in a single column are rotated down, so that the number in the last row moves to the first.
Ivo occasionally feels the urge to move a number to cell and proceeds as follows:
- While is not in column , rotate the row it is in.
- While is not in row , rotate the column it is in.
Here is an example of how to move number to cell , start from the initial configuration:
1 | 2 | 3 | 4 |
5 | 6 | 7 | 8 |
9 | 10 | 11 | 12 |
13 | 14 | 15 | 16 |
1 | 2 | 3 | 4 |
8 | 5 | 6 | 7 |
9 | 10 | 11 | 12 |
13 | 14 | 15 | 16 |
1 | 2 | 3 | 4 |
7 | 8 | 5 | 6 |
9 | 10 | 11 | 12 |
13 | 14 | 15 | 16 |
1 | 2 | 3 | 16 |
7 | 8 | 5 | 4 |
9 | 10 | 11 | 6 |
13 | 14 | 15 | 12 |
Ivo wants to move numbers one after another. Write a program that calculates the number of rotations needed.
Input Specification
The first line contains two integers and , the table dimension and the number of moves.
Each of the following lines contains three integers , and , the description of one move Ivo wants to make. Ivo does the moves in the order in which they are given.
Output Specification
