Analysis of algorithm design principle Quick sort is an improvement on bubble sort. The basic idea of quick sort is to divide the data to be sorted into two independent parts through one-time sorting, in which all the data in one part is smaller than all the data in the other part, and then quickly sort the two fractional data respectively acc ...

1. PassThrough filter: for threshold filtering 1. Introduction of Straight-pass Filter PassThrough filters, as the name implies, use a threshold to directly filter out filters that do not meet the threshold. For example, if there are 100,000 numbers with values ranging from 1 to 100,000 and the pass filter has a threshold value of <50, ...

A A - A Funny Game Meaning: n coins form a circle. Each round can take away one or two adjacent coins. Finally, the player who takes all the coins wins. Alice took the lead and asked who would win. Idea: when n < = 2, Alice can take it all at once, and Alice will win; When n > = 3, no matter Alice takes 1 or 2 coins, Bob can take the c ...

Day 34 540 a single element in an ordered array Give you an ordered array of integers, where each element will appear twice and only one number will appear once. Please find and return the number that appears only once. The solution you design must meet O(log n) time complexity and O(1) space complexity. method Since all elements in the a ...

Depth first traversal of trees and graphs & breadth first traversal of trees and graphs The two traversal methods of tree and graph are algorithms based on the idea of dfs and bfs. Its idea is still recursive, but the traversal object becomes an undirected graph, so there are more precautions in the process of graph construction and sea ...

Interpretation of UNet algorithm principle and implementation of pad U-Net network is a very classic image segmentation network, which originates from medical image segmentation. It has the characteristics of few parameters, fast calculation and strong applicability. It has high adaptability to general scenes. U-Net was first proposed in 2015 ...

Planet A has n cities, numbered from 1 to N, with m two-way roads between them. Each road has A weight limit for vehicles, referred to as weight limit. Now there are q trucks transporting goods. Xiao Ming wants to know the maximum load of each truck under the condition of not exceeding the vehicle weight limit. Input Two integers n,m in the f ...
