Webb27 dec. 2016 · The in-place version actually uses a fairly simple trick: Sort one byte at a time. First sort on the highest byte. That will split the input into 256 partitions. Now recursively sort within each of those partitions using the next byte. Keep doing that until you run out of bytes. Webb9 nov. 2024 · They are both well-known comparison-based, in-place, stable sorting algorithms. Both algorithms are easy to understand and implement. Both have similar runtime complexities.
