Nested loop logic

Outer loop i runs 1..n (rows). Inner loop j runs 1..i, printing one star each — so row i has i stars. Print a newline after the inner loop.

  • Running the inner loop to n instead of i — every row then prints n stars.
  • Forgetting the newline after each row.
Python
n = int(input())
for i in range(1, n + 1):
    print("* " * i)
