This a very simple Yee algorithm 3D FDTD code in C implementing the free space form of Maxwell s equations on a Cartesian grid. There are no internal materials or geometry. The code as delivered simulates an idealized rectangular waveguide by treating the interior of the mesh as free space/air and enforcing PEC (Perfect Electric Conductor) conditions on the faces of the mesh.

ARM下 Implement matrix multiplication of 2 square matrices, with data read from an input file and printed both to the console and to an output file. • Assume a file with correct data (no garbage, characters, etc.). • you must check and provide appropriate execution for 2 extra cases, namely when the matrix size given is either “0” , or when the size is greater than the maximum handled of “5” . In these 2 cases you must implement the following behaviour: o If size = 0, then print a message “Size = 0 is unacceptable” and continue by reading the next size for the next 2 matrices (if not end of file). o If size >5, then print two messages: “Size is too big - unacceptable”. Then read and discard the next (size2 ) integers and continue by reading the next size for the next 2 matrices (if not end of file).

數字運算，判斷一個數是否接近素數 A Niven number is a number such that the sum of its digits divides itself. For example, 111 is a Niven number because the sum of its digits is 3, which divides 111. We can also specify a number in another base b, and a number in base b is a Niven number if the sum of its digits divides its value. Given b (2 <= b <= 10) and a number in base b, determine whether it is a Niven number or not. Input Each line of input contains the base b, followed by a string of digits representing a positive integer in that base. There are no leading zeroes. The input is terminated by a line consisting of 0 alone. Output For each case, print "yes" on a line if the given number is a Niven number, and "no" otherwise. Sample Input 10 111 2 110 10 123 6 1000 8 2314 0 Sample Output yes yes no yes no

* Function: * 1. Replace the first oldstr with newstr in srcstr * Arguments: * IN : * srcstr * oldstr * newstr * OUT : * srcstr * Return: * 1. If find and replace one oldstr with newstr in srcstr , return 1 * 2. If find no oldstr in srcstr , return 0 * 3. If error (malloc return NULL) return -1 * notes: * 1. srcstr should be large size enough.

一個游戲 the hardware for the game includes a number of displays, each with a button and -- a light, that each represent a bin that can store marbles (beans). -- -- The display indicates the number of marbles in each bin at any given time. -- The light indecates that the present bin is not empty and that pushing the -- button is a valid move in the game. -- -- The button for each display indicates that a player takes the marbles from -- the selected bin, and takes them in his hand. The hand is represented by a -- diplay itself (no button). -- -- Each player has a home bin, located on opposite sides of the game.

Due to an increase in demand for and questions about direct disk access for Micrososft platforms, and due to the fact that Microsoft has no API for direct disk access, I am releasing this library much earlier than I intended at that start. I am still working on this code.
