Radix sort: No comparisons required

Sorting is a fundamental operation in computer science, and while many sorting algorithms rely on comparisons, radix sort provides a unique approach that sorts integers without comparisons by grouping numbers into buckets based on their component digits. This makes radix sort particularly effective for sorting data that can be ordered by their digits, such as integers, and it operates by iterating over each digit position, grouping items into buckets, and then flattening these groups to form a sorted array. The tutorial explores the implementation of radix sort using JavaScript, detailing helper functions like `asInteger`, `digitAtPosition`, `digitsCount`, and `maxDigitsCount` to facilitate the sorting process. Unlike comparison-based algorithms, radix sort has a time complexity of O(k•n) and is well-suited for data with a consistent number of digits, but it can be memory-intensive as it creates new arrays for buckets. Additionally, the tutorial presents a modified version of radix sort for alphabetic sorting, which uses padding for strings and demonstrates how radix sort can be adapted to different data types, while also highlighting the importance of space optimization for large data sets.
