What is inside Nested Loops, Grids and Patterns

  1. A loop inside a loop: one row per outer pass
  2. The trace table: j starts again on every row
  3. The right triangle: the inner bound follows the outer
  4. The number pyramid: count the spaces before you print
  5. break leaves one loop, not both
  6. Count the passes before you run
