## How do you sort an array in descending?

**C Program to Sort the Array in Descending Order**

- Create an
**array**of fixed size (maximum capacity), lets say 10. - Take n, a variable which stores the number of elements of the
**array**, less than maximum capacity of**array**. - Iterate via for loop to take
**array**elements as input, and print them. - The
**array**elements are in unsorted fashion, to**sort**them, make a nested loop.

## How do you arrange in descending order in Python?

## How do you sort in ascending order in python without sort function?

**Python** Program to **Sort List in Ascending Order without** using **Sort**. In this program, we are using Nested For Loop to iterate each number in a **List**, and **sort** them in **ascending order**. if(NumList[0] > NumList[1]) = if(67 > 86) – It means the condition is False. So, it exits from If block, and j value incremented by 1.

## What is Sorting and filtering explain with example?

The **filter** tool gives you the ability to **filter** a column of data within a table to isolate the key components you need. The **sorting** tool allows you to sort by date, number, alphabetic order and more. In the following **example**, we will explore the usage of **sorting and filtering** and show some advanced **sorting** techniques.

## How do you sort and filter?

## What is sorting write down the steps to sort the records?

## What is the basic principle of sorting 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**.

## What is bubble sort explain with example?

**Bubble Sort** is the simplest **sorting** algorithm that works by repeatedly swapping the adjacent elements if they are in wrong order. **Example**: First Pass: ( 5 1 4 2 8 ) –> ( 1 5 4 2 8 ), Here, algorithm compares the first two elements, and swaps since 5 > 1.

## Why is insertion sort better than bubble sort?

**Bubble sort** always takes one more pass over array to determine if it's **sorted**. ... **Bubble sort** does n comparisons on every pass. **Insertion sort** does less **than** n comparisons: once the algorithm finds the position where to insert current element it stops making comparisons and takes next element.

## Is bubble sort ever useful?

**Bubble sort** is easy to implement and it is fast enough when you have small data sets. ... Donald Knuth, in his famous "The Art of Computer Programming", concluded that "the **bubble sort** seems to have nothing to recommend it, except a catchy name and the fact that it leads to some interesting theoretical problems".

## Why is bubble sort o n 2?

You are correct that the outer loop iterates **n** times and the inner loop iterates **n** times as well, but you are double-counting the work. ... The inner loop does **O**(**n**) work **on** each iteration, and the outer loop runs for **O**(**n**) iterations, so the total work is **O**(**n2**).
