In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn t kept waiting any longer than necessary for the relatively slow disks.

Problem D:合唱隊形 Time Limit:1000MS Memory Limit:65536K Total Submit:1237 Accepted:437 Language: not limited Description N位同學站成一排,音樂老師要請其中的(N-K)位同學出列,使得剩下的K位同學排成合唱隊形。 合唱隊形是指這樣的一種隊形:設K位同學從左到右依次編號為1,2…,K,他們的身高分別為T1,T2,…,TK, 則他們的身高滿足T1 < T2 < ...< Ti > Ti+1 > … >TK(1<=i<=K)。 你的任務是,已知所有N位同學的身高,計算最少需要幾位同學出列,可以使得剩下的同學排成合唱隊形。 Input 輸入包含若干個測試用例。 對于每個測試用例,輸入第一行是一個整數N(2<=N<=100),表示同學的總數。第二行有N個整數,用空格分隔,第i個整數Ti(130<=Ti<=230)是第i位同學的身高(厘米)。當輸入同學總數N為0時表示輸入結束。 Output 對于每個測試案例,輸出包括一行,這一行只包含一個整數,就是最少需要幾位同學出列。 Sample Input 8 186 186 150 200 160 130 197 220 3 150 130 140 0 Sample Output 4 1

單片機作為一種微型計算機,其內部具有一定的存儲單元(8031除外),但由于其內部存儲單元及端口有限,很多情況下難以滿足實際需求。為此介紹一種新的擴展方法,將數據線與地址線合并使用,通過軟件控制的方法實現數據線與地址線功能的分時轉換,數據線不僅用于傳送數據信號,還可作為地址線、控制線,用于傳送地址信號和控制信號,從而實現單片機與存儲器件的有效連接。以單片機片外256KB數據存儲空間的擴展為例,通過該擴展方法,僅用10個I/O端口便可實現,與傳統的擴展方法相比,可節約8個I/O端口。 Abstract: As a micro-computer,the SCM internal memory has a certain units(except8031),but because of its internal storage units and the ports are limited,in many cases it can not meet the actual demand.So we introduced a new extension method,the data line and address lines combined through software-controlled approach to realize the time-conversion functions of data lines and address lines,so the data lines not only transmited data signals,but also served as address lines and control lines to transmit address signals and control signals,in order to achieve an effective connection of microcontroller and memory chips.Take microcontroller chip with256KB of data storage space expansion as example,through this extension method,with only10I/O ports it was achieved,compared with the traditional extension methods,this method saves8I/O ports.
