Classification of sorting algorithms

Before diving into sorting algorithms, it is important to understand how they are classified in computer science. Sorting algorithms are not all the same; they differ in the way they organise data, the efficiency of their operations, and the types of problems they are best suited to solve. By learning these classifications, we can better understand the trade-offs between different algorithms, such as speed, memory usage, stability, and simplicity. Sorting algorithms can be classified into the following groups

Comparison sorting

Comparison-based sorting algorithms rely on comparing elements in the list to determine their order. These algorithms compare elements using a comparison operator (e.g., less than, greater than) and rearrange the elements based on the results of these comparisons. Most widely used sorting algorithms are comparison-based except for counting sort, which uses a counting-based approach.
