# Data Structures: Question Set – 17

#### What are some disadvantages of Radix Sort?

Some disadvantages of Radix Sort include its reliance on the size of the input data, its requirement for extra space to store intermediate results, and its inability to sort data that cannot be broken down into individual digits.

#### Can Radix Sort be used to sort strings?

Yes, Radix Sort can be used to sort strings by breaking them down into individual characters and sorting them by their ASCII values. However, it may require additional preprocessing steps to ensure that all strings are of equal length.

#### What is Bucket Sort?

Bucket Sort is a non-comparative sorting algorithm that sorts data by dividing it into several buckets and then sorting each bucket individually using another sorting algorithm or recursively applying the bucket sort algorithm. It is a linear time sorting algorithm, and its time complexity is O(n+k), where n is the number of elements to sort and k is the number of buckets.

#### How does Bucket Sort work?

Bucket Sort works by dividing the input array into several buckets, each of which is then sorted individually using another sorting algorithm or by recursively applying the bucket sort algorithm. Once each bucket has been sorted, the sorted elements are concatenated back into the original array.

#### What is the time complexity of Bucket Sort?

The time complexity of Bucket Sort is O(n+k), where n is the number of elements to sort and k is the number of buckets.

#### What is the space complexity of Bucket Sort?

The space complexity of Bucket Sort is O(n+k), where n is the number of elements to sort and k is the number of buckets.

#### Is Bucket Sort stable or unstable?

Bucket Sort can be either stable or unstable depending on the sorting algorithm used to sort the individual buckets.

#### What are some advantages of Bucket Sort?

Some advantages of Bucket Sort include its linear time complexity, its ability to sort numbers with a relatively uniform distribution, and its ease of parallelization.

#### What are some disadvantages of Bucket Sort?

Some disadvantages of Bucket Sort include its dependence on the distribution of input data, its requirement for additional memory to store the buckets, and its inability to sort data that cannot be divided into discrete buckets.

#### Can Bucket Sort be used to sort strings?

Yes, Bucket Sort can be used to sort strings by using a hash function to map each string to a bucket and then sorting the strings within each bucket. However, it may require additional preprocessing steps to ensure that all strings are of equal length.
