| You have encountered a new fancy online auction that offers lots of products. |
| You are only interested in their price and weight. We shall say that product A |
| is strictly preferred over product B if A costs less than B and is not heavier |
| (they may be of equal weight) or if A weighs less and is not more expensive |
| (they can have equal price). |
|
|
| We shall call a product A a bargain if there is no product B such that B is |
| better than A. Similarly, we shall call a product C a terrible deal if there |
| exists no product D such that C is better than D. Note that according to our |
| definitions, the same product may be both a bargain and a terrible deal! Only |
| wacky auctioneers sell such products though. |
|
|
| One day you wonder how many terrible deals and bargains are offered. The |
| number of products, N, is too large for your human-sized brain though. |
| Fortunately, you discovered that the auction manager is terribly lazy and |
| decided to sell the products based on a very simple pseudo-random number |
| generator. |
|
|
| If product i has price Pi and weight Wi, then the following holds for product |
| i+1: |
|
|
| * Pi = ((A*Pi-1 \+ B) mod M) + 1 (for all i = 2..N) |
| * Wi = ((C*Wi-1 \+ D) mod K) + 1 (for all i = 2..N) |
| |
| You carefully calculated the parameters for the generator (P1, W1, M, K, A, B, |
| C and D). Now you want to calculate the number of terrible deals and bargains |
| on the site. |
| |
| ### Input |
| |
| The first line of the input file contains a single integer T: the number of |
| test cases. T lines follow, each representing a single test case with 9 space- |
| separated integers: N, P1, W1, M, K, A, B, C and D. |
| |
| ### Output |
| |
| Output T lines, one for each test case. For each case, output "Case #t: a b", |
| where t is the test case number (starting from 1), a is the number of terrible |
| deals and b is the number of bargains. |
| |
| ### Constraints |
| |
| * 1 ≤ T ≤ 20 |
| * 1 ≤ N ≤ 1018 |
| * 1 ≤ M, K ≤ 107 |
| * 1 ≤ P1 ≤ M |
| * 1 ≤ W_1 ≤ K |
| * 0 ≤ A,B,C,D ≤ 109 |
