0202 - Nested Iteration II: Not a 'grid'
Statement:As you have seen, nested iteration is often used to create two-dimensional grids. But it's actually much more versatile than this, since it can be used to create any repetition of (internally repetitive) elements.
Use a single pair of nested for{} loops to reproduce the pattern illustrated here : a group of six "fans", each of which has ten (oops, eleven! Thanks Moshe!) lines.
