Little H has recently been studying randomized algorithms. Randomized algorithms often use random number generation functions (e.g. random from Pascal and rand from C/C++) to obtain their randomness. In reality, random number functions are not truly "random." Instead, they work off of some specific algorithms.

As such, the following recursive quadratic polynomial is one method:

The algorithm selects nonnegative integers ~x_0~, ~a~, ~b~, ~c~, and ~d~ as its seed values and uses the following recursive calculations to generate a random number.

For any ~i \ge 1~, ~x_i = (a \times x^2_{i-1} + b \times x_{i-1}+c) \bmod d~.

This way, a sequence of nonnegative integers ~\{x_i\}_{i \ge 1}~ of arbitrary length can be obtained. Typically, we can consider this sequence to be random. Using the sequence ~\{x_i\}_{i \ge 1}~, we can use the following algorithm to produce ~\{T_i\}_{i=1}^K~, a random permutation of the numbers ~1~ to ~K~.

1. Initialize ~T~ to the sequence of integers from ~1~ to ~K~.
2. Perform ~K~ swaps on the sequence ~T~. The ~i~-th swap will swap the value of ~T_i~ with the value of ~T_{(x_i \bmod i) + 1}~.

Outside of this base number of ~K~ swaps, little H has made an additional ~Q~ swaps. For the ~i~-th additional swap, little H will choose two positions ~u_i~ and ~v_i~ and swap the values of ~T_{u_i}~ and ~T_{v_i}~.

To check the effectiveness of the random permutation generator, little H designed the following problem:

Little H has an ~N~ row by ~M~ column grid. She initially follows the above process, producing a random permutation ~\{T_i\}_{i=1}^{N \times M}~ of the integers from ~1~ to ~N \times M~ after ~N \times M + Q~ swaps. Then these ~N \times M~ values are then placed back into the grid, row for row, column for column. That is, the cell at column ~j~ of row ~i~ in the original grid will now take on the value of ~T_{(i-1) \times M+j}~.

Afterwards, little H wishes to start from the top-left corner of the grid (i.e. row ~1~, column ~1~), each step moving either right or down under the precondition that she does not move outside of the grid, and reach the bottom-right corner (i.e. row ~N~, column ~M~).

Little H writes down the value of every cell she travels through, ordered from least to greatest. This way, for any valid path, little H can obtain an increasing sequence of length ~N + M - 1~ which we will call the path sequence. Little H wishes to know the lexicographically smallest path sequence that she can obtain.

Input Specification

Line 1 of input consists of five integers ~x_0~, ~a~, ~b~, ~c~, and ~d~, representing the seed values to little H's random number generator.
Line 2 of input consists of three integers ~N~, ~M~, and ~Q~, indicating that little H generates a permutation from ~1~ to ~N \times M~ to fill her ~N \times M~ grid. Also, after little H performs her ~N \times M~ swaps, she will perform an additional ~Q~ swaps.
The final ~Q~ lines will each contain two integers ~u_i~ and ~v_i~, indicating that the ~i~-th additional swap involves swapping ~T_{u_i}~ and ~T_{v_i}~.

Output Specification

The output should consist of one line containing ~N + M - 1~ space-separated positive integers, representing the lexicographically smallest path sequence that little H can obtain.

Explanation

For sample 1, according to the input seed values, the first 12 random numbers of ~x_i~ are:
9 5 30 11 64 42 36 22 1 9 5 30
With these 12 random numbers, little H will perform 12 swap operations, yielding the following:
6 9 1 4 5 11 12 2 7 10 3 8
After the additional 3 swap operations, little H obtains the final permuted sequence of:
12 9 1 7 5 11 6 2 4 10 3 8
This sequence will yield the following grid.

$$\displaystyle \begin{array}{|c|c|c|c|}\hline 12 & 9 & 1 & 7 \\\hline 5 & 11 & 6 & 2 \\\hline 4 & 10 & 3 & 8 \\\hline \end{array}$$

The optimal path sequence is: ~12 \to 9 \to 1 \to 6 \to 2 \to 8~.
