Advanced Numeric Sequence Grid
This program prints a 4x4 grid of alternating squares and cubes.
Problem Statement
Write a Java program that prints a 4x4 grid where even positions show squares and odd positions show cubes.

Explanation
The program increments num sequentially. If odd, cube is printed; if even, square is printed. Nested loops arrange results in grid form. Shows how nested loops can generate advanced numeric sequence grids.
