Introduction to Sorting Algorithms In the world of programming, sorting algorithms act like diligent “organizers,” arranging chaotic data in a specific order. Their applications are extensive; for instance, on e-commerce platforms, sorting algorithms allow products to be sorted by price, sales volume, and other factors, making it easier for users to find their desired items. … Read more

Counting sort is a non-comparison based sorting algorithm suitable for sorting integers, provided that the range of the elements to be sorted is known and relatively concentrated. Its core idea is to count the occurrences of each element and then reconstruct the ordered array based on these counts. Basic Steps of Counting Sort Determine the … Read more
Today’s algorithm problem is to solve the "Palindrome Number" algorithm using C language. Here is my thought process and implementation, let’s take a look. Algorithm Problem Given an integer, determine if it is a palindrome number. A palindrome number is an integer that reads the same forwards and backwards. Algorithm Idea We will use a … Read more
Prelude Mathematical Foundations 1. Functions A function is a type of mapping relationship (correspondence/rule). Since it is a mapping relationship, there must be at least two numbers, one of which participates in the mapping, while the other number establishes a relationship with the mapping result. Typically, we use x and y to represent the two … Read more
Today is the 729th day of learning programming with a slightly cold rain! Hello, everyone! This is the GESP Level 4 Examination question. Day 729 GESP Level 4 Examination in March 2025 True or False Question 8: The time complexity of insertion sort in the best case (already sorted) is O(n^2). Answer: False START OF … Read more
Today’s algorithm problem is to solve the "Integer Reversal" algorithm using C language. Below are my algorithm ideas and implementation. Let’s take a look. Algorithm Problem Given a 32-bit signed integer, reverse it. Algorithm Idea We will use a clever method to solve the integer reversal problem. The idea of the algorithm is to reverse … Read more
