# Quick Answer: How Does Selection Sort Work Example?

## 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..

## 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.

## Which is better selection sort or bubble sort?

Selection sort has achieved slightly better performance and is efficient than bubble sort algorithm. … In selection sort, the sorted and unsorted array doesn’t make any difference and consumes an order of n2 (O(n2)) in both best and worst case complexity. Selection sort is faster than Bubble sort.

## What are the different sorting techniques?

Types of Sorting Algorithms:Quick Sort.Bubble Sort.Merge Sort.Insertion Sort.Selection Sort.Heap Sort.Radix Sort.Bucket Sort.

## What is the best case for selection sort?

n^2Selection sort/Best complexity

## How bubble sort is performed?

Bubble sort, sometimes referred to as sinking sort, is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order. The pass through the list is repeated until the list is sorted.

## 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.

## What are the benefits of sorting?

OTHER LEARNING BENEFITS OF SORTING COLOURSFun, interactive and motivating!Great for fine motor development and hand/eye coordination.Self-correcting and problem solving.Literacy: Connecting the written word with the colour.Language skills: naming labelling and pronunciation.More items…

## Which sorting algorithm is best if the list is already sorted?

insertion sort​Many sorting algorithms are available, but the one which is best suited for the almost sorted array is the insertion sort.

## How do you make a selection sort stable?

Selection sort can be made Stable if instead of swapping, the minimum element is placed in its position without swapping i.e. by placing the number in its position by pushing every element one step forward. In simple terms use a technique like insertion sort which means inserting element in its correct place.

## How do you write a selection sort?

Selection Sort in CExample of Selection Sort.Algorithm for Selection Sort:Step 1 − Set min to the first location.Step 2 − Search the minimum element in the array.Step 3 – swap the first location with the minimum value in the array.Step 4 – assign the second element as min.Step 5 − Repeat the process until we get a sorted array.More items…•

## What is the use of selection sort?

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.

## How insertion sort works with example?

For example, the lower part of an array is maintained to be sorted. An element which is to be ‘insert’ed in this sorted sub-list, has to find its appropriate place and then it has to be inserted there. Hence the name, insertion sort.

## Which is the fastest sorting algorithm?

QuicksortThe time complexity of Quicksort is O(n log n) in the best case, O(n log n) in the average case, and O(n^2) in the worst case. But because it has the best performance in the average case for most inputs, Quicksort is generally considered the “fastest” sorting algorithm.

## Which sort is better insertion or selection?

Conclusion. Among both of the sorting algorithm, the insertion sort is fast, efficient, stable while selection sort only works efficiently when the small set of elements is involved or the list is partially previously sorted.
