A bucket sort algorithm requires that the input is taken from a uniform distribution of numbers and has an average-case running time of O(n). So, depending on the distribution of numbers, it may perform worse then O(n). Here is the pseudocode of the bucket sort algorithm: 1. Make a hash table with a chain resolution (could be a nested list or 2D array) 2. Use the hash function that assigns most significant digits to 'a bucket, a hash table entry. For example, a hash table index floor (nA[i]), where n is a number from 0- the size of the input array, A[i] is an item in the input array A. 3. Sort lists that are created by the chain resolution using insertion sort. Best running time Worst running time ✓ [Choose ] O(n^2) O(nlogn) Q(loan)

A bucket sort algorithm requires that the input is taken from a uniform distribution of numbers and
has an average-case running time of O(n). So, depending on the distribution of numbers, it may
perform worse then O(n).
Here is the pseudocode of the bucket sort algorithm:
1. Make a hash table with a chain resolution (could be a nested list or 2D array)
2. Use the hash function that assigns most significant digits to 'a bucket', a hash table entry. For
example, a hash table index = floor (nA[i]), where n is a number from 0- the size of the input
array, A[i] is an item in the input array A.
3. Sort lists that are created by the chain resolution using insertion sort.
