Discuss in detail the difference between the sliding window algorithm and the KMP algorithm and the scenarios in which they are used.

What is the sliding window algorithm The sliding window algorithm is an algorithm for solving subarray (or substring) problems within an array (or string). The algorithm works by maintaining a fixed-size window (usually two pointers) that slides over the array to find subarrays that match specific criteria. The basic idea of the algorithm is to […]

uni-app is a very easy-to-use table control, which is very useful for layout display.

Usage is very simple, add a line of css to the page /* Introduce table style sheet */ @import “../../lib/helang-table.scss”; Complete code of the page <template> <view class=”content”> <view class=”itme-box”> <view class=”title”>Default</view> <view class=”h-table”> <view class=”h-tr h-tr-3 h-thead “> <view class=”h-td”>Theme</view> <view class=”h-td”>Class name</view> <view class=”h-td”>Remarks</view> </view> <view class=”h-tr h-tr-3″> <view class=”h-td”>Default</view> <view class=”h-td h-td-colspan […]

SpringBoot implements dynamic switching of data sources, which is more elegant!

Recently, when doing business requirements, I need to obtain data from different databases and then write them into the current database, so it involves switching data sources. Originally I wanted to use the dynamic data source SpringBoot starter provided in Mybatis-plus: dynamic-datasource-spring-boot-starter to achieve it. After the results were introduced, it was found that it […]
