These structures are "graceful" according to the RingelÂ–Kotzig conjecture.
These structures are "graceful" according to the RingelÂ–Kotzig conjecture. In-order, pre-order, and post-order are ways to traverse these structures. The height of these structures can be decreased by the DSW algorithm. Sleator and Tarjan invented a self-adjusting type of this structure that changes its shape based on access frequency. A self-balancing type of this data structure named for two colors is quicker than the AVL type. Solving the traveling salesman problem involves constructing the minimum spanning type of this data structure. For 10 points, name this data structure that makes up a forest, and has terminal nodes called leaves
