My List>, for instance, is a little gross and makes fiddling with its innards more complex than I think needs to be. The lower bound for Comparison based sorting algorithm (Merge Sort, Heap Sort, Quick-Sort .. etc) is Ω(nLogn), i.e., they cannot do better than nLogn. Since Radix Sort depends on digits or letters, Radix Sort is much less flexible than other sorts. And the magic of LSD radix sorting is eh, once you do it on the first key then the strings are all sorted. source: GeeksforGeeks.
