The government of a small but important country has decided that the alphabet needs to be streamlined and reordered. Uppercase letters will be eliminated. They will issue a royal decree in the form of a String of B and A characters. The first character in the decree specifies whether a must come ( B )Before b in the new alphabet or ( A )After b . The second character determines the relative placement of b and c , etc. So, for example, "BAA" means that a must come Before b , b must come After c , and c must come After d . Any letters beyond these requirements are to be excluded, so if the decree specifies k comparisons then the new alphabet will contain the first k+1 lowercase letters of the current alphabet. Create a class Alphabet that contains the method choices that takes the decree as input and returns the number of possible new alphabets that conform to the decree. If more than 1,000,000,000 are possible, return -1. Definition

MISRA (The Motor Industry Software Reliability Association 汽車工業軟件可靠性聯會) 是位于英國的一個跨國汽車工業協會,其成員包括了大部分歐美汽車生產商。其核心使命是為汽車工業提供服務和協助,幫助廠方開發安全的、高可靠性的嵌入式軟件。這個組織最出名的成果是所謂的MISRA C Coding Standard,這一標準中包括了127條C語言編碼標準,通常認為,如果能夠完全遵守這些標準,則你的C代碼是易讀、可靠、可移植和易于維護的。最近很多嵌入式開發者都以MISRA C來衡量自己的編碼風格,比如著名的uC/OS-II就得意地宣稱自己99%遵守MISRA標準。而《嵌入式開發雜志》也專門載文號召大家學習。編碼規范通常是一個公司自定的“土政策”,居然有人去做標準,而且還得到廣泛的認可,這不禁引起我強烈的興趣。可惜這份標準的文本需要花錢去買,而且短短幾十頁,要價非常昂貴。MISRA在網上公布了一些文檔,其中有關于MISRA C Coding Standard的Clarification報告,從中間你可以大致猜到MISRA標準本身是什么。

This section contains a brief introduction to the C language. It is intended as a tutorial on the language, and aims at getting a reader new to C started as quickly as possible. It is certainly not intended as a substitute for any of the numerous textbooks on C. 2. write a recursive function FIB (n) to find out the nth element in theFibanocci sequence number which is 1,1,2,3,5,8,13,21,34,55,…3. write the prefix and postfix form of the following infix expressiona + b – c / d + e * f – g * h / i ^ j4. write a function to count the number of nodes in a binary tr

Note that only the PORT is provided and it is assumed that you have the rest of the source for µ C/OS-II from the book or the upgrade.

This book is intended for embedded system programmers, consultants and students interested in real-time operating systems. μC/OS-II is a high performance, deterministic real-time kernel and can be embedded in commercial products (see Appendix F, Licensing). Instead of writing your own kernel, you should consider μC/OS-II. You will find, as I did, that writing a kernel is not as easy as it first looks.

1.有三根桿子A,B,C。A桿上有若干碟子 2.每次移動一塊碟子,小的只能疊在大的上面 3.把所有碟子從A桿全部移到C桿上 經過研究發現,漢諾塔的破解很簡單,就是按照移動規則向一個方向移動金片: 如3階漢諾塔的移動:A→C,A→B,C→B,A→C,B→A,B→C,A→C 此外,漢諾塔問題也是程序設計中的經典遞歸問題
