Overview In JavaScript, we often need to convert a one-dimensional array to a two-dimensional array. This kind of operation is very common in fields such as data processing and visualization. This article will introduce two methods of converting a one-dimensional array into a two-dimensional array, hoping to help readers better understand this process. Method 1: […]

Python programming realizes the shortest distance from point to point, point to line, point to rectangle, and point to any polygon
1. Distance from point to point First of all, the simplest is the distance between two points, just use the distance formula directly import math import matplotlib.pyplot as plt def point_to_point(x1, y1, x2, y2): lineMagnitude = math.sqrt(math.pow((x2 – x1), 2) + math.pow((y2 – y1), 2)) return lineMagnitude 2. Distance from point to line segment The […]
Prompt Engineering | Iterative optimization and improvement of prompt
When trying to write the first prompt, meet the two principles mentioned in the previous blog: clear and clear, and give the system enough time to think. Then you can run it and see the result. If it doesn’t work the first time, the iterative process is to figure out why the instructions weren’t clear […]

Implement a database (DataBase) Go language implementation version from scratch 7. Free list: reuse pages
English source address Since our B-tree is immutable, each update to the kv store will create new nodes on the path instead of updating the current nodes, making some nodes inaccessible from the latest version. We need to reuse these from the old version Inaccessible nodes, otherwise, the database file will grow infinitely. Design Free […]
