In computer science, radix sort is a non-comparative integer sorting algorithm that sorts data with integer keys by splitting its key into individual digits, and comparing individual digits sharing the same significant position. A positional notation is required, but because integers can represent strings of characters (e.g., names or dates) and specially formatted floating point numbers, radix sort is not limited to integers. Radix sort dates back as far as 1887 to the work of Herman Hollerith on tabulating machines.
