Drawing parallelepipeds P46903

Write a program that reads several triplets of natural numbers b, h and d, and for each one prints a parallelepiped of base b, height h and depth d.

Input

Input consists of several triplets of strictly positive natural numbers b, h and d, with h≥ d.

Output

For every triplet, print a parallelepiped of base b, height h and depth d, as it is shown in the example. Print an empty line after each parallelepiped.
