1. Experimental Purpose 1) Familiarize yourself with and master the logical and physical structure of linear tables; 2) Familiarize yourself with and master the storage structure, basic operations and definitions of specific functions of linear chained lists; II. EXPERIMENTAL CONTENTS Design a main menu program with multiple menu items, and ...

Arithmetic expression evaluation A typical problem solved by stack is the evaluation of arithmetic expressions, such as "3 + 4 * 2 - (1 + 1) #". In the process of expression calculation, it is not calculated immediately after reading an operation, but compared with the following operators to determine which one to calculate first. In ...

summary Python Dictionary (dict) is an unordered and variable sequence. Its elements are stored in the form of "key value". In contrast, list s and tuple s are ordered sequences, and their elements are stored next to each other at the bottom. The dictionary type is the only mapping type in Python. "Mapping" is a term ...

dynamic chain Single linked list: //Head node refers to the first node in the linked list, which can be divided into real head node and virtual head node; (1) Real head node: the first node is used to store data (usually the real head node is used). (2) Virtual head node: the first node cannot store data. (3) Header pointer: it is just a ref ...

1, Introduction to linear table Linear table is A finite sequence consisting of zero or more data elements. The characteristic of a linear table is that in a sequence, except for the head and tail elements, each element has With and only one direct precursor, With and only one direct successor, The sequence header element has no direct ...

sort() function: it is a sort function in c++ stl library. Learning to use this function can greatly save us from writing a sort function, such as bubble sort (O(n2)). Moreover, this sort function is written by quick sort, so the time complexity is O(nlogn), so it can also greatly reduce the program running time. Note that the sorting range is ...

Linear table Definition and characteristics of linear table A linear table is a finite sequence of data elements with the same characteristics. Linear list: an ordered sequence composed of n (n > = 0) data elements (nodes) a1,a1,... An. definition: 1. The number n of data elements is defined as the length of the table. 2. When n=0, it ...

1, Basic concepts of queue Note: three elements of data structure - logical structure, data operation and storage structure (physical structure) Different storage structures lead to different implementations of operations 1. Definition of queue A linear table is a finite sequence of n (n > = 0) data elements with the same data type, whe ...

When we practice Java algorithm, we will inevitably encounter some problems. Using some skilled problem-solving methods is much better than not using them. This time, we mainly share the skills about double needles. Double pointers are generally divided into two categories: one is fast and slow pointers, and the other is left and right pointer ...

Binary tree 1. What is a binary tree Binary tree is a kind of tree. Each node can have at most two subtrees, that is, the maximum degree of the node is 2 (node degree: node degree) Some subtrees). 2. Binary tree species Binary search tree: The left side of the current root node is smaller than the root node, and the right side of the ...
