Print Right Triangle Number Pattern Type 3

PRINT PATTERN  6*6*6*6 5*5*5 4*4 3

For any input number N Print the following code – For below code N=4 and Initial value is 3

6*6*6*6
5*5*5
4*4
3

PREREQUISITE:

Basic knowledge in Java programming, usage of loops.

ALGORITHM:

1. Take input from user i.e number of lines required (N value) and initial value ‘a’ and copy n value to ‘t’.
2. Take two loops one for each line (say ‘i’) and other for each digit in a particular line (say ‘j’). i starts from (n+a)-1 and j starts from 1.
3. Here ‘i’ loop is used to access each line from 1 to n and ‘j’ loop is used to print values in each line. j loop is executed until it reaches i value.
4. Print ‘i’ value until the j loop reaches t value and decrement t and .go to next line.
5. Repeat loop until it reaches a value.

CODE IN JAVA:

import java.lang.*;
import java.io.*;
class Main
{
    public static void main (String[]args) throws IOException
    {
        BufferedReader br =new BufferedReader (new InputStreamReader (System.in));
        int n, i, j, a, t;
        System.out.print ("Enter N value:");
        n = Integer.parseInt (br.readLine ());
        t = n;
        System.out.print ("Enter initial Value:");
        a = Integer.parseInt (br.readLine ());
    
        for (i = (n + a) - 1; i >= a; i--)
        {
	        for (j = 1; j <= t; j++)
	        {
	            System.out.print (i);
	        }
	        System.out.println ();
	        t--;
        }
    }
}
