Problem regarding decreasing value in every row

#1

package Section1pattern;

import java.util.Scanner;

public class Pattern27 {

public static void main(String[] args) {
	// TODO Auto-generated method stub

Scanner scn = new Scanner(System.in);
System.out.println(“Enter the number of rows”);
int n = scn.nextInt();
int q = n-1;

int counter = 1;
for(int i = 1 ; i<=n;i++) {
int t = 1;
while(t<=2) {
for(int j =1;j<=q;j++) {
System.out.print("\t");

	}
	if(t!=2) {
		int y=1;
	
		
		for(int r=1;r<=counter;r++) {
			
			System.out.print(y);
			System.out.print("\t");
			y++;
		}
		
		counter=counter+1;
	}
	
		

	t++;
}
System.out.println("\n");
q=q-1;

}
}

}

I am not getting how to decrease the value in every single row. i cant understand how to make that loop.

You don’t need to make a separate loop for this. Inside the loop where you are printing the values for every row, keep a count of the column. So, for every row, till column/2 the value will increase and after that the value will decrease. Use an ‘if-else’ block for this. This has been illustrated in the video as well.
Try altering your code using this logic, and if you not able to, then let me know and I will give more hints.
