Description Vuex provides four commonly used auxiliary functions: the purpose is to map the corresponding data and functions in state(), mutaions{}, actions{}, getters{} in vuex, so that we can be more flexible in the component. Simply use these data and functions mapState mapMutations mapActions mapGetters Usage cases /src/store/index.jsState Manager import axios, { Axios } from […]

Permutation generation algorithm: total permutation of sets
1. Generate an arrangement of 1 ~ n Ideas Try to use recursive thinking to solve the problem: first output all the permutations starting with 1 (this step is a recursive call), then output the permutations starting with 2 (also a recursive call), then the permutations starting with 3… and finally the permutations starting with […]
Analytical properties + permutation rings + minimum cut: 1024T4
http://cplusoj.com/d/senior/p/SS231024D It is equivalent to selecting some replacement rings to perform a displacement. We consider only replacing A. For a ring of size > 1, if you shift it, you can definitely make the bits completely different. So if we permute B, what is the significance of the permutation? It counts the positions of self-loops […]

[Algorithm Training-Backtracking Algorithm 1] [Permutation Problem] Full Permutation, Full Permutation II
Without further ado, just shout a slogan to encourage yourself: Programmers will never be unemployed, programmers go to architecture! The theme of this blog is [Backtracking Algorithm], which is implemented using the basic data structure [array]. The website for this high-frequency question is: CodeTop, and the filtering conditions are: Target company + Last year + […]

Eleven: Vuex, getters, mapState, mapGetters, mapActions, mapMutations, multi-component shared data, vuex modularization
一.vuex 1.vuex introduction What is it? vuex is a vue plug-in that implements centralized state (data) management in Vue. Centralized is like a teacher teaching a group of students, and the state is data; Vuex centrally manages (read and write) the shared data of multiple components in Vue applications, and is suitable for communication between […]
