本文从原理到实践系统地分享了如何高效使用AI编程工具。涵盖其底层机制（如Token计算、工具调用、Codebase索引与Merkle ...

二维码（Quick Response Code，简称QR码）自1994年由日本电装公司发明以来，因其高密度信息承载能力、快速读取特性及开源标准支持，已广泛应用于支付、身份验证、物流追踪、广告营销等多个领域。特别是在移动互联网普及后，智能手机普遍内置摄像头与扫码功能，使得QR码成为连接物理世界与数字服务的重要桥梁。然而，这一便利性亦被网络犯罪分子迅速利用，演变为新型网络钓鱼载体。 2025年下半年， ...

How do you count rooted planar n n-ary trees with some number of leaves? For n = 2 n = 2 this puzzle leads to the Catalan numbers. These are so fascinating that the combinatorist Richard Stanley wrote ...

Design an algorithm and write code to serialize and deserialize a binary tree. Writing the tree to a file is called 'serialization' and reading back from the file to reconstruct the exact same binary ...

Abstract: For increasingly complex real-world optimization problems, a large number of researches have shown that differential evolution (DE) is an effective problem-solving algorithm. Despite its ...

Now that we’re getting into more complex data structures, having more complex operations, it’s helpful to have a tool for visualization. Here’s a tool developed by David Galles, formerly of University ...
