How does radix sort work to efficiently sort elements in a collection?

Radix sort is a non-comparative sorting algorithm that works by grouping elements by their individual digits. It sorts elements by comparing digits at different positions in the numbers, starting from the least significant digit to the most significant digit. This process is repeated for each digit position until all elements are sorted. Radix sort is efficient because it does not rely on comparisons between elements, making it faster than comparison-based sorting algorithms for certain types of data.
