如何使用 C# 找到所有接近于零的唯一四元组？

The simplest way is that we can create four nested loops and check one by one whether the sum of all four elements is zero. If the sum of the four elements is zero, print the elements.

Time complexity - O(n⁴)

- O(1)

We can use an unordered set data structure to store each value of the array. Set offers the advantage of searching for elements in O(1) time. So, for each pair in the array, we will look for the negative value of their sum that may exist in the set. If such an element is found then we can print a triple which will be a pair of integers and the negative value of their sum.

Time complexity - O(n³)

Space complexity - O(n)

Developing with C# .NET: A Practical Guide and ExamplesMay 12, 2025 am 12:16 AM

C# and .NET provide powerful features and an efficient development environment. 1) C# is a modern, object-oriented programming language that combines the power of C and the simplicity of Java. 2) The .NET framework is a platform for building and running applications, supporting multiple programming languages. 3) Classes and objects in C# are the core of object-oriented programming. Classes define data and behaviors, and objects are instances of classes. 4) The garbage collection mechanism of .NET automatically manages memory to simplify the work of developers. 5) C# and .NET provide powerful file operation functions, supporting synchronous and asynchronous programming. 6) Common errors can be solved through debugger, logging and exception handling. 7) Performance optimization and best practices include using StringBuild

C# .NET: Understanding the Microsoft .NET FrameworkMay 11, 2025 am 12:17 AM

.NETFramework is a cross-language, cross-platform development platform that provides a consistent programming model and a powerful runtime environment. 1) It consists of CLR and FCL, which manages memory and threads, and FCL provides pre-built functions. 2) Examples of usage include reading files and LINQ queries. 3) Common errors involve unhandled exceptions and memory leaks, and need to be resolved using debugging tools. 4) Performance optimization can be achieved through asynchronous programming and caching, and maintaining code readability and maintainability is the key.

Mastering C# .NET Design Patterns: From Singleton to Dependency InjectionMay 09, 2025 am 12:15 AM

Design patterns in C#.NET include Singleton patterns and dependency injection. 1.Singleton mode ensures that there is only one instance of the class, which is suitable for scenarios where global access points are required, but attention should be paid to thread safety and abuse issues. 2. Dependency injection improves code flexibility and testability by injecting dependencies. It is often used for constructor injection, but it is necessary to avoid excessive use to increase complexity.
