1. Introduction: Solve this question in AcWing: 823. Arrangement In this question, an integer n is given, and the numbers 1 to n are required to be arranged in a row, and all arrangements are output in lexicographic order. This questionmainly examines the application of total permutation and lexicographic order, and is solved through the […]

Full permutation algorithm (recursive and dictionary)
An algorithmic proposition: given a string S[0…N-1], design an algorithm to enumerate the full arrangement of S. For example: 123, the full arrangement is: 123,132,213,231,312,321 I am just ignorant. It took me a day and a half to finally sort out the dictionary. I can’t see the code written by the master. There are still […]
R language to draw chromosome mutation position distribution map, RIdeogram package
Chromosome distribution map of mutation sites The content shared today is to use the RIdeogram package to draw a chromosome locus distribution map, and introduce a method to display differential loci. In genetic research, genotype information at certain locations on the genome is obtained through sequencing and other methods. As shown in the table below, […]
Cuckoo optimization algorithm integrating Cauchy mutation and adaptive Levy flight, improved cuckoo, MATLAB code
Friends often leave messages in the background asking: Can the algorithm improved by the author be used to write a paper? The answer is: Of course! No need to add citations! If my article can help you write a paper, it will be the author’s honor! The cuckoo optimization algorithm is a very classic optimization […]
P9578「Cfz Round 1」Permutation
Go to Luogu to read my blog Ideas We need to try to minimize the maximum value minus the minimum value of the sum of two adjacent numbers. First think about how to minimize the maximum value. for n n n, minimum must be placed on both sides 1 1 1 and 2 2 2. […]
CF1872D Plus Minus Permutation
Go to Luogu to read my blog Ideas Another CF scam question. for x x The number selected by x is enlarged as much as possible. For y y We try to make the number selected by y as small as possible, but it may be x x x and y y Just put the […]

Anti-kill confrontation – ShellCode online + callback compilation and execution + confusion mutation algorithm
C/C + + —ShellCode–Free-kill confrontation Introduction: Shellcode is a piece of code used to exploit software vulnerabilities. Shellcode is a hexadecimal machine code, so it is named because it often allows attackers to obtain a shell. We often generate payloads of specified programming languages in CS, and this payload contains a piece of hexadecimal machine […]
Adding Mutations to Our Schema
Author: Zen and the Art of Computer Programming 1. Introduction The general goal of GraphQL mutations is to update the server-side state of a resource based on the input provided by the client. However, adding mutations to our schema requires additional work and knowledge. In this article, we will explore how to add mutations to […]
