Is nst necessary

#1

int n = 7;
int row = 1;

	while(row <= n) {
		int col = 1;
		while(col <= row) {
			System.out.print("* ");
			col++;
		}
		System.out.println();
		row++;
	}

I have gotten the exact same answer using this code, So I was wondering whether the use of the extra variable nst is beneficial in some way?

@devanshsood2000_b7de8cac3ff0472d It is not necessary to use nst variable here but to build up the concept and to get a pattern to solve all types of pattern questions. I would advice that you use nst here also. However it is not necessary
