Radix sort vs Counting sort vs Bucket sort. What's the difference?

Question

I am reading the definitions of radix, counting and bucket sorts and it seems that all of them are just the code below:

public static void sort(int[] a, int maxV         


        

Answer 1

Radix sort uses a form of counting sort as subroutine (ok, can use, but most often it will be counting sort).

Countingsort is a special form of bucket sort, as kasavbere answered.

And Bucketsort divides the keys into buckets and then sorts the buckets individually.
