Example of a complete traversal of a set container:
Original container:  10 20 30 40 50 60
Output during traversal: 10 20 21 30 40 41 42 43 50 60 61 80 81 82 83 84 85 86 87 
Final container:  10 20 21 30 40 41 42 43 50 60 61 80 81 82 83 84 85 86 87

Example of a complete traversal of a multiset container:
Original container:  10 20 30 40 50 60
Output during traversal: 10 20 20 21 30 40 40 40 41 41 42 43 50 60 60 61 80 80 80 81 81 81 82 82 83 83 84 85 86 87 
Final container:  10 20 20 21 30 40 40 40 41 41 42 43 50 60 60 61 80 80 80 81 81 81 82 82 83 83 84 85 86 87
