DMOPC '21 Contest 8 P4 - Grid Operations
View as PDFYou have found a strange device that shows a  grid of numbers. The rows are numbered from 
 to 
, and the columns are numbered from 
 to 
. Initially, the number at the intersection of the 
-th row and the 
-th column is equal to 
.
The grid is partitioned into an  grid of 
 subgrids. These subgrids are coloured white or black in a checkerboard pattern, with the top-left 
 subgrid coloured white.
You notice that the device can perform  types of operations on the grid, which are:
- Type 
1: In every row, swap the numbers on each of theadjacent pairs of cells with the same colour.
 - Type 
2: In every row, swap the numbers on each of theadjacent pairs of cells with different colours.
 - Type 
3: In every column, swap the numbers on each of theadjacent pairs of cells with the same colour.
 - Type 
4: In every column, swap the numbers on each of theadjacent pairs of cells with different colours.
 - Type 
5: Rotate every whitesubgrid clockwise and rotate every black
subgrid counterclockwise.
 
Now you wonder: What is the final state of the grid after performing  operations of types 
 in order?
Constraints
Subtask 1 [10%]
There are only type 1, 3, and 5 operations.
Subtask 2 [25%]
There are only type 1 and 2 operations.
Subtask 3 [10%]
There are only type 1, 2, 3, and 4 operations.
Subtask 4 [55%]
No additional constraints.
Input Specification
The first line contains  space-separated integers: 
, 
, and 
.
The next  lines each contain an integer 
, the type of an operation to perform.
Output Specification
Output  lines, each containing 
 space-separated integers: The final grid after performing all the operations.
