This program prints a pyramid alternating numbers, alphabets, and stars.
Problem Statement
Write a Java program that prints a pyramid of 6 rows alternating numbers, alphabets, and stars cyclically.

Program Output

3 B * 4 C *

12 K * 13 L * 14 M * 15 N * 16 O *
Explanation
Within each row, the position j%3 cycles through printing a number, an alphabet, or a star, so the pyramid rows themselves show a repeating three-symbol cyclic sequence rather than switching per row.
