Program Output
1 A * 4 B * 7 C * 10 D * 13 E * 16 F * 19 G * 22 H * 25 I * 28 J * 31 K * 34 L *
Explanation
A running index (i*n+j)%3 is computed for every cell in row-major order, cycling through printing a number, an alphabet, or a star, producing a strictly repeating three-symbol sequence across the whole grid.
