We tend to value some of the tools of language, but ignore some of the underlying logic problems, resulting in the time to write code is unclear, affecting the quality of the code. So I decided to do some C language or Java programming exercises in my spare time, to exercise my logic of thinking. And synchronize the exercises in the blog, on the one hand, in order to

This article is quoted from the "new data structure exercises and analysis" (Li Chunbao, etc.) the 1th chapter.1. Basic concepts of data structure 1.1Data is a symbolic representation of an objective thing, which in computer science refers to all the symbols that can be entered into a computer and processed by a computer program. For example, integers, real numbers, and strings are data.1.2 Data elementsA data element, also known as a node, is a basic

the Getresultset function in the code implementation.Scaling issuesWhat if there might be the same elements in the sequence, and each element can be used at most once? There are two changes compared to the previous question: 1) Each element can be used at most once, and the next recursion cannot start at the current position, but from the next one. 2) because the sequence contains equal elements, even if each element is used at most one time, duplicate combinations may occur, so in order to av
