Question

Write different programs to print the given series:
1000 81 512 49 216 25 64 9 8 1​

Answer 1

Using JAVA:

Program:

public class oh {

public static void main(String[] args) {

 /*

  * 1000 81 512 49 216 25 64 9 8 1​

  */

 int a = 10;

 int j = 9;

 for (int i = 1; i < 6; i++) {

  System.out.print(Math.round(Math.pow(a, 3)) + " ");

  System.out.print(Math.round(Math.pow(j, 2)) + " ");

  a = a - 2;

  j = j - 2;

 }

}

}

Using Python:

Program:

a=10

b=9

for i in range (1,6):

   print(a**3, b**2, end=" ")

   a-=2

   b-=2

Explanation:

In JAVA I used .round method to convert decimal to int.

Answer 2

Required Answer:-

Question:

• Write a program to print the series:- 1000 81 512 49 216 25 64 9 8 1

Solution:

This is written in Java.

1. public class JavaBrainly {
2. public static void main(String[] args) {
3. int a=3, b=2;
4. for(int i=10;i>=1;i--)
5. {
6. System.out.print((int)Math.pow(i,a)+" ");
7. int c=a;
8. a=b;
9. b=c;
10. }
11. }
12. }

This is written in Python.

1. a,b=3,2
2. for i in range(10,0,-1):
3. print(i**a,end=" ")
4. a,b=b,a

Explanation:

Logic is as follows,

1000 = 10³

81 = 9²

512 = 8³ and so on.

So, it's like n³, n²

After each iteration, variable 'i' is raised to the power a where a = 3 and b = 2. At the same time, the values of a and b are swapped. So, variable 'i' is raised to the power 3 and then to the power 2, then again 3,2 and so on.

Output is attached for verification.
