問題描述 設有n種不同面值的硬幣，各硬幣的面值存于數組T[1:n]中。現要用這些面值的硬幣來找錢，可以實用的各種面值的硬幣個數不限。當只用硬幣面值T[1],T[2],…,T[i]時，可找出錢數j的最少硬幣個數記為C(i,j)。若只用這些硬幣面值，找不出錢數j時，記C(i,j)=∞。 編程任務 設計一個動態規劃算法，對1≤j≤L，計算出所有的C( n,j )。算法中只允許實用一個長度為L的數組。用L和n作為變量來表示算法的計算時間復雜性 數據輸入 由文件input.txt提供輸入數據。文件的第1行中有1個正整數n（n<=13），表示有n種硬幣可選。接下來的一行是每種硬幣的面值。由用戶輸入待找錢數j。 結果輸出 程序運行結束時，將計算出的所需最少硬幣個數輸出到文件output.txt中。

AES在AVR單片機上的實現 資源要求 Program: 4492 bytes (6.9％ Full) (.text + .data + .bootloader) Data: 745 bytes (9.1％ Full) (.data + .bss + .noinit) 可以在AVR Studio中模擬運行 AES加密和解密 在AVR Studio 中模擬運行 Ctrl+F7 后，模擬執行到main入口處 按F5后, 知道到加密完成 可以看出加密的結果 再按F10,執行解密, 可以看出input數組恢復了 原來的結果

對任意給定的文法G 構造LR(1) 項目集規范族，其中要實現CLOSURE(I)、GO(I,X)、FIRST 集合等。在此基礎上， 構造了LR（1）分析表。然后對輸入的句子進行語法分析，給出接受或出錯報告。 程序采用文件輸入輸出方式。其中包括兩個輸入文件：文法grammar.txt，以及 輸入串input.txt；兩個輸出文件：項目集items.txt 和文法的LR(1)分析表 action_table.txt。由于語法分析的結果只給出接受或錯誤報告，比較簡

This article introduces how to construct a Hospital Ward Information System with three-tiered technology. The System applies to UML, BDE, MIDAS, distributed compute theory and a special architecture to make such functions: patients check in and check out, prescription input, drug-delivery at center pharmacy and information of patient manage with computer networking.

RS232.C was written to provide all of the basic functionality needed to employ serial I/O in any application written with Borland C language compilers. Some features are: 1. Ease of use. No assembly language or library files are used and a simple "#include" statement is all that is required to access all of the functions provided. 2. Both input and output are buffered and interrupt driven for efficiency. 3. Serial ports 1 - 4 are supported on PC, AT and PS/2 compatibles.Chained interrupts used on port 3 and 4 are allowed for so as not to interfere with devices such as a mouse or printer. Transmission speeds of 110 to 115200 baud are available. 4. Detection and utilization of hardware buffered UARTs (NS16550AF etc.) found in some machines is automatic. 5. Interrupt driven hardware and XON/XOFF flow control is provided for. 6. All source code is included. RS232.C can be used with all memory models.

a sample WDM stream class video capture driver that supports two IEEE 1394 digital cameras. The same driver may be able to support other digital cameras that conform to 1394-based Digital Camera Specification from 1394 Trade Association. Digital camera supported by dcam.sys is a data source that produces digital image data without any other input connection. It manifests itself in a DirectShow graph as a WDM Streaming Capture Device and as a capture filter that has output capture stream supporting image sizes of 320x240 with a UYVY color space. Its de-compressor, Msyuv.dll, is part of the OS delivery, and it can convert image data format from UYVY to RGB16, RGB8, or to a Direct Draw surface if the video card supports UYVY format.

MS-Clustering is designed to rapidly cluster large MS/MS datasets. The program merges similar spectra (having similar m/z values ?within a given tolerance), and creates a single consensus spectrum as a representative. The input formats accepted are: dta, mgf, mzXML. The output format is mgf.
