Required Answer:-

Question:

Write a program to print the pattern.

1 2 3 4

2 3 4

3 4

4

Solution:

Here is the code.

1. public class Pattern {
2. public static void main(String[] args) {
3. for(int i=1;i<=4;i++)
4. {
5. for(int j=i;j<=4;j++)
6. System.out.print(j+" ");
7. System.out.println();
8. }
9. }
10. }

Explanation:

• Outer loop will run from i = 1 to n where 'i' is the control variable.
• Inner loop will run from j = i to n.
• Here, n is the number of rows. For example, if n = 4, inner loop will print 1 to 4 at first iteration of outer loop then it will print 2 to 4 at second iteration and so on.

Output is attached.
