You are a student looking for a job.
Today you had an employment examination for an IT company.
They asked you to write an efficient program to perform several operations.
First, they showed you an `N \times N` square matrix and a list of operations.
All operations but one modify the matrix, and the last operation outputs the character in a specified cell.
Please remember that you need to output the final matrix after you finish all the operations.

Followings are the detail of the operations:

- WR r c v
- (Write operation) write a integer v into the cell (r,c) (
`1 \leq v \leq 1,000,000`) - CP r1 c1 r2 c2
- (Copy operation) copy a character in the cell (r1,c2) into the cell (r2,c2)
- SR r1 r2
- (Swap Row operation) swap the r1-th row and r2-th row
- SC c1 c2
- (Swap Column operation) swap the c1-th column and c2-th column
- RL
- (Rotate Left operation) rotate the whole matrix in counter-clockwise direction by 90 degrees
- RR
- (Rotate Right operation) rotate the whole matrix in clockwise direction by 90 degrees
- RH
- (Reflect Horizontal operation) reverse the order of the rows
- RV
- (Reflect Vertical operation) reverse the order of the columns

First line of each testcase contains nine integers.
First two integers in the line, N and Q, indicate the size of matrix and the number of queries, respectively `(1 \leq N,Q \leq 40,000)`.
Next three integers, A B, and C, are coefficients to calculate values in initial matrix `(1 \leq A,B,C \leq 1,000,000)`,
and they are used as follows: `A_{r,c} = (r * A + c * B) mod C` where r and c are row and column indices, respectively `(1\leq r,c\leq N)`.
Last four integers, D, E, F, and G, are coefficients to compute the final hash value mentioned in the next section `(1 \leq D \leq E \leq N, 1 \leq F \leq G \leq N, E - D \leq 1,000, G - F \leq 1,000)`.
Each of next Q lines contains one operation in the format as described above.

Output a hash value h computed from the final matrix B by using following pseudo source code.

h <- 314159265 for r = D...E for c = F...G h <- (31 * h + B_{r,c}) mod 1,000,000,007

where "<-" is a destructive assignment operator, "for i = S...T" indicates a loop for i from S to T (both inclusive), and "mod" is a remainder operation.
