- 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
- Example Input:
- 5
- 5 1 4 5 7 1 0 1 2
- 3 1 3 3 3 1 0 1 1
- 8 1 3 3 3 1 0 1 2
- 13 5 7 5 9 1 3 2 5
- 11 2 3 5 7 11 13 17 19
- Example Output:
- Case #1: 3 3
- Case #2: 3 3
- Case #3: 2 3
- Case #4: 2 2
- Case #5: 3 1
