Radix Sort is a non-comparative sorting algorithm that organizes numbers by processing individual digits. It works by sorting the numbers from the least significant digit to the most significant digit, using a stable sorting algorithm like Counting Sort for each digit. This method allows it to efficiently handle large sets of data. The algorithm is particularly effective for sorting integers or strings of fixed length. Its time complexity is generally O(nk), where n is the number of elements and k is the number of digits in the largest number. This makes Radix Sort faster than traditional comparison-based sorting methods for specific types of data.
