解決時(shí)鐘問(wèn)題，acm競(jìng)賽題 A weird clock marked from 0 to 59 has only a minute hand. It won t move until a special coin is thrown into its box. There are different kinds of coins as your options. However once you make your choice, you cannot use any other kind. There are infinite number of coins of each kind, each marked with a number d ( 0 <= 1000 ), meaning that this coin will make the minute hand move d times clockwise the current time. For example, if the current time is 45, and d = 2. Then the minute hand will move clockwise 90 minutes and will be pointing to 15. Now you are given the initial time s ( 0 <= s <= 59 ) and the coin s type d. Write a program to find the minimum number of d-coins needed to turn the minute hand back to 0.

這個(gè)例子如果運(yùn)行,將在仿真的PC窗口中的第1,2,3行顯示一些信息后,在隨機(jī)位置顯示 1 ~ 5 .由于keil c51默認(rèn)不支持重入函數(shù),它的重入函數(shù)使用仿真的重入棧而不使用系統(tǒng)棧,而Small RTOS 51沒(méi)有進(jìn)行重入棧管理,所以在TaskA~TaskE雖然及其相似,但不能合并. 注意:(1)在KEIL C51 工程中,我已經(jīng)把輸出文件目錄設(shè)在e:\temp中,您可以在Project->Options for Target "Target 1"的output頁(yè)點(diǎn)擊Select Folder for Objects...和Listing頁(yè)點(diǎn)擊Select Folder for Listing...改變. (2)編譯時(shí)會(huì)有5個(gè)警告,其中一個(gè)是因?yàn)闆](méi)有使用一個(gè)系統(tǒng)函數(shù)OSSendSignal引起,它可以忽略.另4個(gè)是禁止任務(wù)間變量覆蓋分析引起,必須忽略.感謝網(wǎng)友John X.

LibTorrent is a BitTorrent library written in C++ for *nix, with a focus on high performance and good code. The library differentiates itself from other implementations by transfering directly from file pages to the network stack. On high-bandwidth connections it is able to seed at 3 times the speed of the official client. The client uses ncurses and is ideal for use with screen or dtach. It supports saving of sessions and allows the user to add and remove torrents.

When created, this DLL does not export any symbols. As a result, it will not produce a .lib file when it is built. If you wish this project to be a project dependency of some other project, you will either need to add code to export some symbols from the DLL so that an export library will be produced, or you can check the "doesn t produce lib" checkbox in the Linker settings page for this project.
