Original Khojo Papers practice question — not from a past board paper.
Answer
for (int i = 1; i <= n; i++) { for (int j = 1; j <= i; j++) System.out.print("*"); System.out.println(); }
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The outer loop controls the rows and the inner loop the number of stars in each, which is why the inner limit depends on i.
