We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.
Atheros無線芯片AR-6000系列wince 6驅動源代碼(這東西我也沒用過別問我,我是搜別的wince資源搜到的)

Windows CE Embedded CE 6.0 driver installation.
1. Unzip the installation file onto your system (called installation directory below)
2. Create an OS design or open an existing OS design in Platform Builder 6.0.
a. The OS must support the SD bus driver and have an SD Host Controller driver (add these from Catalog Items).
b. Run image size should be set to allow greater than 32MB.
3. a. From the Project menu select Add Existing Subproject...
b. select AR6K_DRV.pbxml
c. select open
This should create a subproject within your OS Design project for the AR6K_DRV driver.
4. Build the solution.

1) Write a function reverse(A) which takes a matrix A of arbitrary dimensions as input and returns a matrix B consisting of the columns of A in reverse order. Thus for example, if
A = 1 2 3 then B = 3 2 1
4 5 6 6 5 4
7 8 9 9 8 7
Write a main program to call reverse(A) for the matrix A = magic(5). Print to the screen both A and reverse(A).
2) Write a program which accepts an input k from the keyboard, and which prints out the smallest fibonacci number that is at least as large as k. The program should also print out its position in the fibonacci sequence. Here is a sample of input and output:
Enter k>0: 100
144 is the smallest fibonacci number greater than or equal to 100.
It is the 12th fibonacci number.
