How to print this pattern

[kuldeep sidhu]

I came across this small programming question of printing the following pattern

1
3*2
4*5*6
10*9*8*7

I was trying but i could not achieve it.
I was trying in the following way..

public static void main(String[] args) {
		int i,j,k=1;
		
		for(i=1;i<=4;i++){
			if(i%2 == 0){
				for(j=1;j<=i;j++,k++){
					System.out.print(k);
				}
				System.out.println();
			}else{
				for(j=1;j<=i;j++,k++){
					System.out.print(k);
				}
				System.out.println();
			}
		}
	}

My thought is to if the line number is even, will print the letters in reverse order, but seems it is not working. Could someone please help.

The loop in your if statement and your else statement look exactly the same to me. I think you intended to reverse one.

I am using this in if condition

if(i%2 == 0){
				int temp_k=k;
				for(j=1;j<=i;j++,k--){
					System.out.print(k+i-1);
				}
				System.out.println();
				k=temp_k+j-1;
			}

This is working as expected. I just get this working by debugging again and again. But to me, this seems bit complicated. Do you have any other simple way of doing the same.

And also i am bit confused about putting *. If i am adding it before printing the letter,it will add at the start of each line. And same with printing after the letter, it will append at the end of each line. How to achieve the desired output.

Yes, and you almost had it before you started changing things. Read Jeanne's response again. Carefully.
