## How do you arrange 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
- STEP 6: PRINT arr[i]
- STEP 7: REPEAT STEP 8 to STEP 9 UNTIL i
- STEP 8: REPEAT STEP 9 UNTIL j

## Can we sort array in order of N?

Yes. If you do not have any limitations regarding space complexity then you can sort the array with o(n) time complexity. Suppose you have an array of k (let k =10) elements.

**How do I sort numbers in ascending order?**

Sort quickly and easily

- Select a single cell in the column you want to sort.
- On the Data tab, in the Sort & Filter group, click. to perform an ascending sort (from A to Z, or smallest number to largest).
- Click. to perform a descending sort (from Z to A, or largest number to smallest).

### How do you check if an array is in ascending order?

Check array sorted or not using a function

- int isArraySorted(int [], int);
- int main() {
- scanf(“%d”, &n);
- for (i = 0; i < n; i++) scanf(“%d”, &s[i]);
- r = isArraySorted(s, n);
- if (r == 1) printf(“The array is sorted in ascending order.\
- return 0; }
- int isArraySorted(int s[], int n) { int a = 1, d = 1, i = 0;

### What is the best way to sort an array?

The time complexity of Quicksort is O(n log n) in the best case, O(n log n) in the average case, and O(n^2) in the worst case. But because it has the best performance in the average case for most inputs, Quicksort is generally considered the “fastest” sorting algorithm.

**How do you sort numbers in a digit?**

The idea is simple:

- you take the current digit of the number you want to sort(let’s call it N)
- you go through all digits in already sorted number(let’s call it S)
- if current digit in S is less than current digit in N, you just insert the digit in the current position in S. Otherwise, you just go to the next digit in S.

#### How can I sort an array alphabetically?

To sort an array of objects by some key alphabetically in descending order, you only need to add as prefix a – (minus) symbol at the beginning of the key string, so the sort function will sort in descending order:

#### How do I sort array in Java?

To use the Arrays class in a program to sort an array, undertake the following steps: Use the import java.util.*; statement to make all of the java.util classes available in the program. Create the array. Use the sort() method of the Arrays class to rearrange an array.

## What is Array sort?

Array sorting is the process of taking the individual elements of an array and arranging them in some type of logical order according a series of rules defined by the user.
