北京大学ACM比赛题目 In 1742, Christian Goldbach, a German amateur mathematician, sent a letter to Leonhard Euler in which he made the following conjecture: Every even number greater than 4 can be written as the sum of two odd prime numbers. For example: 8 = 3 + 5. Both 3 and 5 are odd prime numbers. 20 = 3 + 17 = 7 + 13. 42 = 5 + 37 = 11 + 31 = 13 + 29 = 19 + 23. Today it is still unproven whether the conjecture is right. (Oh wait, I have the proof of course, but it is too long to write it on the margin of this page.) Anyway, your task is now to verify Goldbach s conjecture for all even numbers less than a million.

4. Write a program that sorts three integers. The integers are entered from the console and stored in variables num1, num2 and num3, respectively. The program sorts the numbers so that num1 <= num2 <= num3.

This folder has some scritps that you may find usefull. All of it comes from questions that I ve received in my email. If you have a new request/question, feel free to send it to marceloperlin@gmail.com. But please, don t ask me to do your homework. Passing_your_param0 This folder contains instructions (and m files) for passing you own initial parameters to the fitting function. I also included a simple simulation script that will create random initial coefficients (under the proper bounds) and fit the model to the data.

The control uses javascript to handle number formatting as you keep typing and does the validation as well. For one of our requirement, we needed a javascript based control that did formatting as the users kept typing. Google search only yielded script that did formatting on focus change events only. So I went about creating a new control myself.

Exuberant Ctags is a multilanguage reimplementation of the much-underused ctags(1) program and is intended to be the mother of all ctags programs. It generates indexes of source code definitions which are used by a number of editors and tools. The motivation which drove the development of Exuberant Ctags was the need for a ctags program which supported generation of tags for all possible C language constructs (which no other ctags offers), and because most were easily fooled by a number of preprocessor contructs.

This file contains a C++Builder 4 project called SimplyChaos-X ver 3.1 (SCX31). SCX31 is an encryption tool. I designed it as my graduation paper work. SCX31 is a symmetric stream cipher built on chaos function, one time pad cipher and inspiration from Ground Effect (aviation). The key length can be up to 40 characters (320 bits).
