Which type of sorting is worst?

Sorting algorithms

Algorithm	Data structure	Time complexity:Worst
Heap sort	Array	O(n log(n))
Smooth sort	Array	O(n log(n))
Bubble sort	Array	O(n2)
Insertion sort	Array	O(n2)

What sorting algorithms are unstable?

Some examples of stable algorithms are Merge Sort, Insertion Sort, Bubble Sort, and Binary Tree Sort. While, QuickSort, Heap Sort, and Selection sort are unstable sorting algorithms.

Which sorting technique has Least Worst case?

Time Complexities of Sorting Algorithms:

Algorithm	Best	Worst
Insertion Sort	Ω(n)	O(n^2)
Selection Sort	Ω(n^2)	O(n^2)
Heap Sort	Ω(n log(n))	O(n log(n))
Radix Sort	Ω(nk)	O(nk)

Is bubble sort a stable algorithm?

Yes
Bubble sort/Stable

Is insertion sort a stable algorithm?

Insertion sort/Stable

Is bubble sort the slowest?

With a worst-case complexity of O(n^2), bubble sort is very slow compared to other sorting algorithms like quicksort. The upside is that it is one of the easiest sorting algorithms to understand and code from scratch.

Which is the fastest sorting algorithm in C++?

Quicksort
The 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 sorting algorithm is slowest worst case time?

The Slowest Sorting Algorithms

• The Slowest Sorting Algorithms.
• 3-Way QuickSort (Dutch National Flag)
• Sort an array of 0s, 1s and 2s.
• Sort an array of 0s, 1s and 2s (Simple Counting)
• Segregate 0s and 1s in an array.
• Segregate Even and Odd numbers.

What sorting algos have their best and worst case times equal?

What is the fastest known sort algorithm for absolute worst case? I don’t care about best case and am assuming a gigantic data set if that even matters. Tell us more about your specific scenario so people can suggest pros and cons of common sort algorithms.
