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 bubble sort an array in descending order in C?

“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. }

Which sorting algorithm is best for descending order?

Among the classical sorting algorithms, heap sort will do well when the input turns out to be (almost) sorted in descending order, as then the max-heap construction phase will involve (almost) no swaps (while the most swaps would occur when the input was already sorted in ascending order).

Is array sorted descending?

The only way to sort a primitive array in descending order is, first sort the array in ascending order and then reverse the array in place. This is also true for two-dimensional primitive arrays. Convert your primitives to their respective objects.

What is bubble sort algorithm in C++?

Bubble sort is a sorting algorithm that compares two adjacent elements and swaps them until they are not in the intended order. Just like the movement of air bubbles in the water that rise up to the surface, each element of the array move to the end in each iteration. Therefore, it is called a bubble sort.

How do you make descending order in C++?

Sort an array in descending order in C++ The default comparator used is std::less<> , which sorts the container in ascending order using operator< . We can use std::greater<> to sort in descending order, which delegates the call to operator> .

What is meaning of ascending and descending order?

Descending order means the opposite of ascending order. It means the process of arranging numbers so that they are going from the largest to the smallest. Descending means “going down”, so descending order means that the numbers are going down.

What are the best sorting algorithms in C?

Insertion sort using C. Insertion sort is one of those algorithms which are quite easy to implement and give good results.

  • Shell sort using C. The shell sort is a rather queer algorithm.
  • Quicksort using C. The next algorithm that should be considered is the quicksort.
  • Heap sort using C.
  • Merge sort using C.

    • What is the worst case of bubble sort?

    S (N) depends on the distribution of elements. Θ (N^2) is the Worst Case Time Complexity of Bubble Sort. This is the case when the array is reversely sort i.e. in descending order but we require ascending order or ascending order when descending order is needed.

    What is a simple bubble sort program in C?

    C++ Program to Implement Bubble Sort. Bubble Sort is comparison based sorting algorithm. In this algorithm adjacent elements are compared and swapped to make correct sequence. This algorithm is simpler than other algorithms, but it has some drawbacks also. This algorithm is not suitable for large number of data set.

    What’s an example of a bubble sort algorithm?

    First Pass: Hence after first pass,the largest element will be at the end.

  • Second Pass: In the second pass,2nd largest element will be at n-1 place.
  • Third Pass: In third pass the result will be the same as all the elements have been sorted. In bubble sort,we use 2 loops.
