## What is selection sort good for?

Selection sort can be good at checking if everything is already sorted.

It is also good to use when memory space is limited.

This is because unlike other sorting algorithms, selection sort doesn’t go around swapping things until the very end, resulting in less temporary storage space used..

## What is the disadvantage of counting sort?

Advantages and disadvantages is the size of the helper array (range of distinct values). … Second and the major disadvantage is that counting sort can be used only to sort discrete values (for example integers), because otherwise the array of frequencies cannot be constructed.

## What is the disadvantage of selection sort?

The main advantage of the selection sort is that it performs well on a small list. … The primary disadvantage of the selection sort is its poor efficiency when dealing with a huge list of items. Similar to the bubble sort, the selection sort requires n-squared number of steps for sorting n elements.

## Why bubble sort is bad?

Bubble Sort is one of the most widely discussed algorithms, simply because of its lack of efficiency for sorting arrays. If an array is already sorted, Bubble Sort will only pass through the array once (using concept two below), however the worst case scenario is a run time of O(N²), which is extremely inefficient.

## Which is better insertion sort or bubble sort?

well bubble sort is better than insertion sort only when someone is looking for top k elements from a large list of number i.e. in bubble sort after k iterations you’ll get top k elements. However after k iterations in insertion sort, it only assures that those k elements are sorted. Though both the sorts are O(N^2).

## What is the slowest sorting algorithm?

HeapSort: It is the slowest of the sorting algorithms but unlike merge and quick sort it does not require massive recursion or multiple arrays to work. Merge Sort: The merge sort is slightly faster than the heap sort for larger sets, but it requires twice the memory of the heap sort because of the second array.

## What is best sorting algorithm?

Quicksort is one of the most efficient sorting algorithms, and this makes of it one of the most used as well. The first thing to do is to select a pivot number, this number will separate the data, on its left are the numbers smaller than it and the greater numbers on the right.

## What is the main disadvantage of bubble sort?

The main disadvantage of the bubble sort method is the time it requires. With a running time of O(n^2), it is highly inefficient for large data sets. Additionally, the presence of turtles can severely slow the sort.

## How can you increase the efficiency of a bubble sort?

A better version of bubble sort, known as modified bubble sort, includes a flag that is set if an exchange is made after an entire pass over the array. If no exchange is made, then it should be clear that the array is already in order because no two elements need to be switched. In that case, the sort should end.
