In Go language web development, choosing the right routing library is crucial. Chi and HttpRouter are both lightweight routing solutions favored by developers, each with its own characteristics suitable for different scenarios.Among them, Chi is a feature-rich modular router built on the standard library net/http, known for its modular design and strong middleware support. It … Read more
Today, we will delve into the two “permutation wizards” in the C++ standard library— the next_permutation and prev_permutation functions. They are like gymnasts in the world of numbers, elegantly transforming sequences into all possible permutations! 🎯 Function Usage Instructions 📋 Function Signatures // Default comparison using <bool next_permutation(BidirectionalIterator first, BidirectionalIterator last);bool prev_permutation(BidirectionalIterator first, BidirectionalIterator last);// … Read more

Written by Teacher Wu (with six years of experience in teaching children’s programming, having guided many students to win provincial and national competition awards) This guide is based on real experiences. What is GESP? Why is it worth taking? GESP is a programming ability level certification launched by CCF (China Computer Federation), equivalent to a … Read more
The programming task is to implement a function that takes a matrix of size m x n, and returns all elements of the matrix in diagonal traversal order as an array. Input example: mat = [[1,2,3],[4,5,6],[7,8,9]]Output example: [1,2,4,7,5,3,6,8,9]Example 2:Input example: mat = [[1,2],[3,4]]Output example: [1,2,3,4]Start solving the problem Thoughts and Algorithm The sum of the … Read more

If we need to find a specific number in an array, we can use the binary search method. We can understand binary search through a number guessing game. When we are trying to find 45 in the range of 1 to 100, we guess the middle number, which is 50. We compare the guessed number … Read more
1. Introduction to the LibraryIn Python, we treat time as a first-class citizen using datetime and pandas.Timestamp; in Go, time is divided into three components: time.Time, time.Duration, and time.Location. Consider Go’s time package as the “Swiss Army knife of time for Python programmers,” capable of performing tasks in a zero-dependency binary:• Parsing ISO-8601 timestamps from … Read more
