Answer 1

Required Answer:-

Question:

• Write a program to display the given pattern.

Solution:

Here comes the program.

1. In Java.

public class Pattern {

 public static void main(String[] args) {

    int i, j;

    for(i=9;i>=1;i-=2)  {

       for(j=9;j>=i;j-=2)

          System.out.print(j+" ");

    System.out.println();

    }

 }

}

2. In Python.

for i in range(9,0,-2):

for j in range(9,i-1,-2):

 print(j,end=" ")

print()

3. In C

#include <stdio.h>

int main() {

   int i, j;

   for (i=9;i>=1;i-=2)  {

      for(j=9;j>=i;j-=2)

         printf("%d ", j);

      printf("\n");

   }

   return 0;

}

4. In C++

#include <iostream>

using namespace std;

int main()   {

int i,j;

for(i=9;i>=1;i-=2)  {

 for(j=9;j>=i;j-=2)

 cout <<j<<" ";

cout << endl;

}

return 0;

}

Algorithm:

1. START
2. Iterate i in range 9 to 1.
3. Iterate j in range 9 to i.
4. Display the value of j. Decrease the value of j by 2.
5. Print a new line after displaying the row.
6. Decrease the value of i by 2.
7. STOP
