What are the disadvantages of merge sort and quick sort?
The worst case complexity of quick sort is O(n2) as there is need of lot of comparisons in the worst condition. In merge sort, worst case and average case has same complexities O(n log n). Usage with datasets : Merge sort can work well on any type of data sets irrespective of its size (either large or small).
What is a disadvantage of selection sort?
What is the disadvantage of selection sort? Explanation: As the input size increases, the performance of selection sort decreases. Explanation: Selection sort is insensitive to input, hence 4(n-1) iterations. Whereas bubble sort iterates only once to set the flag to 0 as the input is already sorted.
What is difference between quick sort and merge sort?
The main difference between quicksort and merge sort is that the quicksort sorts the elements by comparing each element with an element called a pivot while merge sort divides the array into two subarrays again and again until one element is left. Sorting is the method of arranging data in a particular order.

Why is bubble sort 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.
What are the disadvantages of bucket sort?
Here are a few disadvantages of bucket sort:
- As mentioned above, you can’t apply it to all data types because you need a good bucketing scheme.
- Bucket sort’s efficiency is sensitive to the distribution of the input values, so if you have tightly-clustered values, it’s not worth it.
What are the advantages and disadvantages of quick sort?
Advantages of Quicksort Its average-case time complexity to sort an array of n elements is O(n lg n). On the average it runs very fast, even faster than Merge Sort. It requires no additional memory. Disadvantages of Quicksort Its running time can differ depending on the contents of the array.
What are the disadvantages of quick sort in Python?
Disadvantages of Quicksort Its running time can differ depending on the contents of the array. Quicksort’s running time degrades if given an array that is almost sorted (or almost reverse sorted). Its worst-case running time, O(n2) to sort an array of n elements, happens when given a sorted array. It is not stable.
Is quicksort really that bad?
For sufficiently random datasets, Quicksort works. The worst case is when your data is all the same (eg. All 1s). I imagine it’s nearly as bad if your dataset is not very diverse as ell (eg. All 1s and 2s) as it will lead to very unbalanced partitions.
What is the difference between quickquick sort and merge sort?
Quick sort is in-place sorting algorithm where as merge sort is not in-place. In-place sorting means, it does not use additional storage space to perform sorting. In merge sort, to merge the sorted arrays it requires a temporary array and hence it is not in-place.
