The problem is to paint n houses with three colors such that no two adjacent houses have the same color. A cost matrix is given, and the goal is

Original link: https://hsiaofongw.notion.site/N-permutations-4a27cfbf1e1942be982fcc8d1f0e4336 This article introduces how to use a linked list to generate N-element permutations, and provides C++ code implementation. The article also discusses the situation where there are repeated elements, and gives the corresponding code implementation. Finally, the article briefly introduces other applications of the linked list data structure. This article is transferred

Original link: https://hsiaofongw.notion.site/C-493c63d36190434aa87290a498e0aea9 This article introduces the concept of declaration in C language, as well as the syntax and parsing process of the declaration statement. Through multiple cases, it helps readers understand different forms of declarators, such as pointers, arrays, functions, etc. The article also introduces how the parser converts the declaration statement into an

By implementing the Walkable interface and the IsEqual function, any type that implements the Walkable interface can be compared, including custom structures, trees, slices, files, etc. As long as a type is Walkable, and the value visited during the Walk can

At the same time, it also introduces the easy-to-use API provided by
