## Is merge sort better than quick?

Merge sort is more efficient and works faster than quick sort in case of larger array size or datasets.

Quick sort is more efficient and works faster than merge sort in case of smaller array size or datasets..

## What is an array Mcq?

A) An array address is the address of first element of array itself. … B) An array size must be declared if not initialized immediately. C) Array size is the sum of sizes of all elements of the array.

## What is the best case complexity of selection sort?

n^2Selection sort/Best complexity

## Which is not a sorting technique?

Bubble sort is an example of in-place sorting. However, in some sorting algorithms, the program requires space which is more than or equal to the elements being sorted. Sorting which uses equal or more space is called not-in-place sorting. Merge-sort is an example of not-in-place sorting.

## 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 the best algorithm for sorting?

QuicksortQuicksort 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 are the types of array?

What are various types of arrays? Explain themOne dimensional (1-D) arrays or Linear arrays: In it each element is represented by a single subscript. The elements are stored in consecutive memory locations. … Multi dimensional arrays: (a) Two dimensional (2-D) arrays or Matrix arrays: In it each element is represented by two subscripts.

## What is the best case efficiency of bubble sort?

The space complexity for Bubble Sort is O(1), because only a single additional memory space is required i.e. for temp variable. Also, the best case time complexity will be O(n), it is when the list is already sorted.

## What are the advantages and disadvantages of selection sort?

## What is the advantages of selection sort over other sorting techniques?

What is the advantage of selection sort over other sorting techniques? Explanation: Since selection sort is an in-place sorting algorithm, it does not require additional storage.

## What is the advantage of bubble sort over other sorting techniques Mcq?

Explanation: Optimised Bubble sort is one of the simplest sorting techniques and perhaps the only advantage it has over other techniques is that it can detect whether the input is already sorted. It is faster than other in case of sorted array and consumes less time to describe whether the input array is sorted or not.

## What are disadvantages of array?

Disadvantages of ArraysThe number of elements to be stored in an array should be known in advance.An array is a static structure (which means the array is of fixed size). … Insertion and deletion are quite difficult in an array as the elements are stored in consecutive memory locations and the shifting operation is costly.More items…•

## Which algorithm is better for Sorting between bubble sort and quicksort?

Given that average case for Bubble Sort is the worst case for Quick Sort, it is safe to say that Quick Sort is the superior sorting algorithm. For short arrays (under 1,000 elements), the benefits of Quick Sort are minimal, and might be outweighed by it’s complexity, if the goal is readability.

## What is the best time complexity of bubble sort Mcq?

What is the best time complexity of bubble sort? Question 10 Explanation: The bubble sort is at its best if the input data 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 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.

## Which method is used to sort the elements in bubble sort?

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.

## 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.

## Why is bubble sort slow?

The algorithm traverses a list and compares adjacent values, swapping them if they are not in the correct order. With a worst-case complexity of O(n^2), bubble sort is very slow compared to other sorting algorithms like quicksort.

## What are the disadvantages of array Mcq?

What are the disadvantages of arrays? Explanation: Arrays are of fixed size. If we insert elements less than the allocated size, unoccupied positions can’t be used again. Wastage will occur in memory.

## Which is the easiest sorting algorithm?

Bubble SortBubble Sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in wrong order.
