In this paper, we will pick up the routine of sub sequence problem. In fact, there are two kinds of templ ...

This paper is a collection of notes after learning the basic sorting algorithm, which is not entirely original. Personal learning ability is limited. The pictures are made by myself. There may be errors in words and pictures. If found, I hope to point out. Since some leaders have conducted in-depth analysis of various algorithms, this blog is o ...

C language sorting algorithm 1. Bubble sorting Bubble Sort is A simple sort algorithm. It repeatedly visits the sequence to be sorted, compares two elements at A time, and exchanges them if their order (e.g. from large to small and from A to Z) is wrong. #include <stdio.h> void bubble_sort(int arr[], int len) { int i, j, temp; ...

array Arrays is a tool class that operates on arrays. Common member methods public static String toString(int[] a) //Convert array to string public static void sort(int[] a) //Sort the array public static int binarySearch(int[] a,int key) //Binary search The toString() source code is as follows: public static String toString(int[] a) { ...

1. Introduction to heap sorting Heap sorting is a sort algorithm designed with heap as the data structure. Heap sorting is an optional sort with the worst, best, and average time complexity of O(nlogn), which is also an unstable sort. Large Top heap and Small Top heap A heap is a complete binary tree with the following properties: Each ...

1. Simulated annealing algorithm Simulated annealing algorithm draws lessons from the idea of statistical physics. It is a simple and general heuristic optimization algorithm, and has probabilistic global optimization performance in theory. Therefore, it has been widely used in scientific research and engineering. Annealing is a process in whi ...

Stack Definition: a stack is a linear table whose insertion and deletion operations are limited to one end of the table. It is usually called the top of the stack and the bottom of the stack. When there are no elements in the table, it is called empty stack. Example: suppose stack S=(a1, a2, a3,... an), then a1 is called the bottom element ...
