Explanation:
import java.util.Scanner;
public class SortArray {
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner sc = new Scanner(System.in);
System.out.println("Enter Size Of Array");
int size = sc.nextInt();
int[] arr = new int[size]; // creating array of size
read(arr); // calling read method
sort(arr); // calling sort method
print(arr); // calling print method
}
// method for read array
private static void read(int[] arr) {
Scanner sc = new Scanner(System.in);
for (int i = 0; i < arr.length; i++) {
System.out.println("Enter " + i + "th Position Element");
// read one by one element from console and store in array
arr[i] = sc.nextInt();
}
}
// method for sort array
private static void sort(int[] arr) {
for (int i = 0; i < arr.length; i++) {
for (int j = 0; j < arr.length; j++) {
if (arr[i] < arr[j]) {
// Comparing one element with other if first element is greater than second then
// swap then each other place
int temp = arr[j];
arr[j] = arr[i];
arr[i] = temp;
}
}
}
}
// method for display array
private static void print(int[] arr) {
System.out.print("Your Array are: ");
// display element one by one
for (int i = 0; i < arr.length; i++) {
System.out.print(arr[i] + ",");
}
}

Answer:
1. #include <stdio.h>
2. int main()
3. {
4. int k;
5. int j;
6. int i;
7. int array[7];
8. array[0] = 1;
9. for (i = 1; i < 9; ++i)
10. {
11. array[i] = array[i-1]*2;
12. for (j=0; j < i; ++j)
13. {
14. printf("%d ",array[j]);
15. }
16. for (k=i-2; k > -1; --k)
17. {
18. printf("%d ", array[k]);
19. }
20. printf("\n");
21. }
22. return 0;
23. }
Explanation:
- From line 1 to 3 we start the main function
- From line 4 to 7 we declare the variables that we are going to be using throughout the program including an array of 7 positions
- On line 8 we initialize the array with one to match the sequence
- From line 9 to 10 we create a for loop to create the 9 sequences of numbers
- On line 11 we assign values to the array by taking the previous value and multiplying it by 2, this way we can create the sequence 1,2,4,8,32...
- From line 12 to 15 we print the ordered array
- From line 16 to 19 we print the inverse array minus one
- On line 20 we print an enter
