Can bubble sort be done in descending order?

Can bubble sort be done in descending order?

Just because you are sorting in descending order doesn’t mean you have to use a descending loop for bubble sort. The reversed loop of for (int i = 0; i < n; i++) is for (int i = n-1; i >=0; i–)… . There is no point in reverse-looping here.

How do you write a bubble sort in descending order?

“bubble sort descending order in c” Code Answer

  1. // C program for implementation of Bubble sort.
  2. #include
  3. void swap(int *xp, int *yp)
  4. {
  5. int temp = *xp;
  6. *xp = *yp;
  7. *yp = temp;
  8. }

Is bubble sort ascending or descending?

In bubble sort, with every pass, the largest element bubbles up to the end of the list if the array is sorted in ascending order. Similarly for the list to be sorted in descending order, the smallest element will be in its proper place at the end of every pass.

How do you write a bubble sort algorithm?

Algorithm for optimized bubble sort

  1. bubbleSort(array)
  2. n = length(array)
  3. repeat.
  4. swapped = false.
  5. for i = 1 to n – 1.
  6. if array[i – 1] > array[i], then.
  7. swap(array[i – 1], array[i])
  8. swapped = true.

What is bubble sort with example?

Advertisements. Bubble sort is a simple sorting algorithm. This sorting algorithm is comparison-based algorithm in which each pair of adjacent elements is compared and the elements are swapped if they are not in order.

What is the order of growth for bubble sort algorithm?

If the given array has to be sorted in ascending order, then bubble sort will start by comparing the first element of the array with the second element, if the first element is greater than the second element, it will swap both the elements, and then move on to compare the second and the third element, and so on.

Is bubble sort stable?

YesBubble sort / Stable

How do you arrange a decreasing number?

Arranging numbers (or other items) in descending order means to arrange them from largest to smallest. The numbers 12, 5, 7, 10, 1, 160 arranged in descending order are 160, 12, 10, 7, 5, 1.

What are descending numbers?

Descending Order Meaning If the information is sorted from highest to lowest, it is said to be in descending order. For example 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 are arranged in descending order. In other words, if the numbers are arranged from the largest to the smallest number, it is said to be in descending order.

How do you explain bubble sort method?

Bubble sort is a basic algorithm for arranging a string of numbers or other elements in the correct order. The method works by examining each set of adjacent elements in the string, from left to right, switching their positions if they are out of order.

What is the order of time complexity for the bubble sort Mcq?

The time complexity would remain unchanged as we can pass through the list only in O(n) time and also it will be sorted in O(n 2) because maximum time for comparison and sorting will be O(n 2) in case of bubble sort .

Which sort improves on the bubble sort by reducing the number of swaps?

insertion sort
Number of swaps reduced than bubble sort. For smaller values of N, insertion sort performs efficiently like other quadratic sorting algorithms.

Which is slowest sorting procedure?

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

How can I improve my 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.
