C# Rotate the square matrix

In this blog post, a C# solution is presented for rotating a square matrix, a problem that the author encountered during an interview. The provided code demonstrates a straightforward approach to this problem by defining two methods: Rotate and RotateItem. The Rotate method is responsible for iterating through the matrix and calling the RotateItem method for each element, while also handling the padding to ensure that the inner matrix is rotated correctly. The RotateItem method, on the other hand, takes care of swapping the elements in the matrix to achieve the desired rotation. By sharing this solution, the author aims to help fellow developers who may face a similar problem in the future. The code is easy to understand and can be used as a reference or starting point for further exploration of matrix manipulation techniques in C#. Readers are encouraged to study the provided code, try it out, and think about possible optimizations or alternative approaches to this problem. How would...--GPT 4

Get unique random numbers in C#

本篇博客介绍了如何在C#中生成唯一的随机数。作者首先构建了一个简单的素数检测方法,并通过该方法生成一个素数序列。接着,编写了一个检测E值是否正确的方法,以及从自然数中找到有效E值的方法。在此基础上,作者实现了将输入值N分解为两个素数P和Q的方法,并通过P和Q得到有效的D和E值。 为了检验所得到的P、Q、D和E值是否有效,作者编写了一个函数,该函数在获取正确的P、Q、D和E值时返回true,失败时返回false。最后,通过调用I ^ d % N来生成随机数序列。由于输入的N值可能无效,因此还需要跳过所有无效输入并找到其附近的最近N值。 博客中提供了一个完整的示例,展示了如何使用这些方法生成唯一的随机数。通过运行示例,我们可以看到输出的随机数序列既随机又唯一。这种方法在需要生成不重复随机数的场景中非常有用。 那么,这种生成随机数的方法是否有局限性?在实际应用中,我们可能需要考虑性能和效率问题。此外,是否有其他更简洁或者更通用的方法来生成唯一随机数呢?在阅读本文后,希望读者能够对这些问题进行思考并尝试寻找答案。--GPT 4
