2.1 Fundamentals of Mathematics1. Mastering the concept of O (N)2. In any analysis that requires a large o representation, various simplifications are possible, and low-order items are usually automatically ignored and constants can be discarded2.2 Models1. Assumptions made about the simulator:1. The simulator does any simple work (addition, subtraction, assignment, comparison) that takes exactly one time unit2. The simulator has unlimited memory, no

Preface: This essay is about XML parsing.Body:1. There are 22 ways of parsing xml: DOM: Once the entire XML data is loaded into memory for parsing, it is more suitable for parsing small files SAX: Starting from the root element, in order to parse an element down, it is more suitable for parsing large files 2. There are many kinds of XML parsing schemes in iOS:2-1. Third-Party framework:LIBXML2: pure C language, which is included by default
