What is the time complexity of the diamond pattern?
It is O(N^2), as both the top half and bottom half take O(N^2) time. The sum is O(2N^2), which simplifies to O(N^2).

A composite pattern is a complex visual shape that is built by combining two or more simpler patterns, like triangles or pyramids, back-to-back.
Mentally split it in half horizontally. The top half is a standard centered pyramid. The bottom half is an inverted centered pyramid.
The top half prints the widest row. If the bottom half started at N, it would duplicate the widest row, making the center of the diamond too thick.
