1 ion-item-divider Item dividers are block elements that can be used to separate items in a list. They are similar to list headers, but instead of just being placed at the top of the list, they should be placed between the items. <ion-list> <ion-item-group> <ion-item-divider> <ion-label> Section A</ion-label> </ion-item-divider> <ion-item> <ion-label>A1</ion-label> </ion-item> <ion-item> <ion-label>A2</ion-label> </ion-item> […]

[TopK problem] Heap-based method & divide-and-conquer strategy-based method
Description: TopK problem: For a given array, select the largest/smallest k elements, or select the kth largest/kth smallest element; This article summarizes two implementation methods, namely Heap-based implementation method: Different from heap sorting, only by constructing a heap containing k elements, the largest/minimum k elements are finally obtained. Method based on divide and conquer strategy: […]
Here comes the problem: after the database is divided into tables, the query is too slow. How to optimize it?
Said before: In the Nien community, many friends reported that Sharding-JDBC paging query is extremely slow. How to deal with it? There are many, many friends who have reported this issue. And this question is also the core problem of the interview. Some time ago, some friends reported that they encountered this problem during the […]
Convex Hull Problem – Divide and Conquer Method Python Implementation
Convex hull problem. Given n points on the plane, find a minimum point set such that the convex polygon composed of the point set surrounds all n points. Based on the divide-and-conquer strategy, an algorithm is designed to solve the convex hull problem. Implement the algorithm and test it. Divide and conquer algorithm idea: If […]

[JAVA] Large integer multiplication (divide and conquer method)
Table of Contents Introduction Algorithm ideas Improve ideas Specific implementation ideas Supplementary ideas Complete code statement Introduction Large integer multiplication is a method for computing the multiplication of two very large integers, often beyond what computer hardware can handle directly. In this case, we need to use some special algorithms to deal with this type […]
[C++ code] Merge intervals, use the minimum number of arrows, divide strings, monitor binary trees, greedy algorithms – Code Thoughts
In the explanation [Greedy Algorithm: Rebuilding the Queue Based on Height, we mentioned that using vector (dynamic array in C++) to perform insert operations is time-consuming. Intuitively, the insert operation of the array is O(n), and the time complexity of the overall code is O(n^2). For ordinary arrays, once the size is defined, it cannot […]
