In each grid, draw a collection of non-overlapping paper clips, either 3, 4, or 5 units long, with rounded parts on both ends and 1 square from one end. The numbers below and to the right of the grid give the total number of rounded parts in that row or column. The first puzzle is solved as an example.

6. | 7. | 8. | 9. | 10. |

11. | 12. | 13. | 14. | 15. |

16. | 17. | 18. | 19. | 20. |
