RSA算法 :首先, 找出三個數, p, q, r, 其中 p, q 是兩個相異的質數, r 是與 (p-1)(q-1) 互質的數...... p, q, r 這三個數便是 person_key，接著, 找出 m, 使得 r^m == 1 mod (p-1)(q-1)..... 這個 m 一定存在, 因為 r 與 (p-1)(q-1) 互質, 用輾轉相除法就可以得到了..... 再來, 計算 n = pq....... m, n 這兩個數便是 public_key ，編碼過程是, 若資料為 a, 將其看成是一個大整數, 假設 a < n.... 如果 a >= n 的話, 就將 a 表成 s 進位 (s

Computes estimates for the number of forests of a graph, input as a 0-1 incidence matrix. Notes: Compile in C++, "g++ -o span_forest span_forest.c". The program does not demand that the matrix is symmetric with 0 diagonal, but uses only the upper triangular part.

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.

The XML Toolbox converts MATLAB data types (such as double, char, struct, complex, sparse, logical) of any level of nesting to XML format and vice versa. For example, >> project.name = MyProject >> project.id = 1234 >> project.param.a = 3.1415 >> project.param.b = 42 becomes with str=xml_format(project, off ) "<project> <name>MyProject</name> <id>1234</id> <param> <a>3.1415</a> <b>42</b> </param> </project>" On the other hand, if an XML string XStr is given, this can be converted easily to a MATLAB data type or structure V with the command V=xml_parse(XStr).

Java Extreme Programming Cookbook offers more than just a collection of cut-and-paste code. Each recipe also includes explanations of how and why the approach works, so you can adapt the techniques to similar situations. One of the biggest challenges facing developers today is sorting through the wide variety of tools available form various source and figuring out how to them effectively. The recipes in Java Extreme Programming Cookbook showcase how to use the most important features of these XP tools. Many of these tools are geared towards unit testing, while others are invaluable for continuous integration with these practical examples, you ll be able to choose the most effective tools to accomplish your goals, then implement them in a cohesive development environment quickly.

本代碼為編碼開關代碼，編碼開關也就是數字音響中的 360度旋轉的數字音量以及顯示器上用的（單鍵飛梭開 關）等類似鼠標滾輪的手動計數輸入設備。 我使用的編碼開關為5個引腳的，其中2個引腳為按下 轉輪開關（也就相當于鼠標中鍵）。另外3個引腳用來 檢測旋轉方向以及旋轉步數的檢測端。引腳分別為a,b,c b接地a，c分別接到P2.0和P2.1口并分別接兩個10K上拉 電阻，并且a，c需要分別對地接一個104的電容，否則 因為編碼開關的觸點抖動會引起輕微誤動作。本程序不 使用定時器，不占用中斷，不使用延時代碼，并對每個 細分步數進行判斷，避免一切誤動作，性能超級穩定。 我使用的編碼器是APLS的EC11B可以參照附件的時序圖 編碼器控制流水燈最能說明問題，下面是以一段流水 燈來演示。
