Efficient sample sort and the average case analysis of pesort core. For example, n students might be assigned integer scores in some range, such as 0 to 100, and are then placed into ranges or buckets based on these scores. The buckets are then sorted individually and then concatenated together.

Integer sorting algorithms can also be used to sort text strings for example, since each string can be converted. Indeed there are perhaps greater similarities between radix sort and bucket sort, than there are between counting sort and bucket sort. Since it runs in linear time on so bucket sort is faster than the comparison based algorithms like merge sort or quick sort just like counting sort, bucket sort also makes some assumption about the input data beforehand like data should be.
