給定兩個集合A、B，集合內的任一元素x滿足1 ≤ x ≤ 109，并且每個集合的元素個數不大于105。我們希望求出A、B之間的關系。 任 務 ：給定兩個集合的描述，判斷它們滿足下列關系的哪一種： A是B的一個真子集，輸出“A is a proper subset of B” B是A的一個真子集，輸出“B is a proper subset of A” A和B是同一個集合，輸出“A equals B” A和B的交集為空，輸出“A and B are disjoint” 上述情況都不是，輸出“I m confused!”

如果整數A的全部因子(包括1，不包括A本身)之和等于B；且整數B的全部因子(包括1，不包括B本身)之和等于A，則將整數A和B稱為親密數。求3000以內的全部親密數。 *題目分析與算法設計 按照親密數定義，要判斷數a是否有親密數，只要計算出a的全部因子的累加和為b，再計算b的全部因子的累加和為n，若n等于a則可判定a和b是親密數。計算數a的各因子的算法： 用a依次對i(i=1~a/2)進行模運算，若模運算結果等于0，則i為a的一個因子；否則i就不是a的因子。 *

源代碼\用動態規劃算法計算序列關系個數 用關系"<"和"="將3個數a，b，c依次序排列時，有13種不同的序列關系： a=b=c,a=b<c,a<b=v,a<b<c,a<c<b a=c<b,b<a=c,b<a<c,b<c<a,b=c<a c<a=b,c<a<b,c<b<a 若要將n個數依序列，設計一個動態規劃算法，計算出有多少種不同的序列關系， 要求算法只占用O(n),只耗時O(n*n).

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

We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.

Design patterns are elegant, adaptable, and reusable solutions to everyday software development problems. Programmers use design patterns to organize objects in programs, making them easier to write and modify. C# Design Patterns: A Tutorial is a practical guide to writing C# programs using the most common patterns. This tutorial begins with clear and concise introductions to C#, object-oriented programming and inheritance, and UML diagrams. Each chapter that follows describes one of twenty-three design patterns, recommends when to use it, and explains the impact that it will have on the larger design. The use of every pattern is demonstrated with simple example programs. These programs are illustrated with screen shots and UML diagrams displaying how the classes interact. Each of these programs is available on the companion CD-ROM and can be run, examined, edited, and applied.
