## How do you put an array in ascending order in Java?

**Algorithm**

- STEP 1: START.
- STEP 2: INITIALIZE arr[] ={5, 2, 8, 7, 1 }.
- STEP 3: SET temp =0.
- STEP 4: PRINT “Elements of Original Array”
- STEP 5: REPEAT STEP 6 UNTIL i<arr.length. //for(i=0; i<arr.length; i++)
- STEP 6: PRINT arr[i]
- STEP 7: REPEAT STEP 8 to STEP 9 UNTIL i<arr.length. …
- STEP 8: REPEAT STEP 9 UNTIL j<arr.length.

## How do you sort an array in ascending order?

**ALGORITHM:**

- STEP 1: START.
- STEP 2: INITIALIZE arr[] ={5, 2, 8, 7, 1 }..
- STEP 3: SET temp =0.
- STEP 4: length= sizeof(arr)/sizeof(arr[0])
- STEP 5: PRINT “Elements of Original Array”
- STEP 6: SET i=0. REPEAT STEP 7 and STEP 8 UNTIL i<length.
- STEP 7: PRINT arr[i]
- STEP 8: i=i+1.

## How do you rearrange arrays in Java?

**Approach(Naive Approach):**

- Navigate the numbers from 0 to n-1.
- Now navigate through array.
- If (i==a[j]) , then replace the element at i position with a[j] position.
- If there is any element in which -1 is used instead of the number then it will be replaced automatically.
- Now, iterate through the array and check if (a[i]!=

## How can you tell if an array is in ascending order?

For all elements, **if the element is equal to or less than its next element**; we can conclude that the array is sorted in ascending order. Case 2: If it does not satisfy even for the single element, the array is not in ascending order.

## How do you sort ascending in Java?

**Java Program to Sort the Array in an Ascending Order**

- import java.util.Scanner;
- public class Ascending _Order.
- {
- public static void main(String[] args)
- {
- int n, temp;
- Scanner s = new Scanner(System. in);
- System. out. print(“Enter no. of elements you want in array:”);

## Is it possible to sort the elements of an array?

**It is not possible to obtain sorted array**.

## How do you sort numbers in ascending order C?

**The program output is also shown below.**

- /*
- * C program to accept N numbers and arrange them in an ascending order.
- #include <stdio.h>
- void main()
- {
- int i, j, a, n, number[30];
- printf(“Enter the value of N n”);
- scanf(“%d”, &n);

## Which sorting algorithm is best?

Time Complexities of Sorting Algorithms:

Algorithm | Best | Worst |
---|---|---|

Bubble Sort | Ω(n) | O(n^2) |

Merge Sort | Ω(n log(n)) | O(n log(n)) |

Insertion Sort | Ω(n) | O(n^2) |

Selection Sort | Ω(n^2) | O(n^2) |

## How do you change the order of an array?

**6 Answers**

- uasort() — Sort an array with a user-defined comparison function and maintain index association.
- uksort() — Sort an array by keys using a user-defined comparison function.
- usort() — Sort an array by values using a user-defined comparison function.

## What are the types of arrays?

There are three different kinds of arrays: **indexed arrays, multidimensional arrays, and associative arrays**.

## Can we change the starting index of an array from 0 to 1 in any way?

Just like in most languages arrays are indexed from 0. You better get used to it, there is no workaround. Base Index of Java **arrays is always 0.** **It cannot be changed to 1**.
