6. Draw a graph (picture) of the binary tree of letters that has been implemented as an array of classes with a data item, left and right child indices as is shown below. Assume that root has index 0 . 7. A full binary tree of height $\mathrm{N}$ has how many leaves? 8. For the tree shown: a) List the nodes that have $\mathrm{Q}$ as an ancestor. b) List the children of J. c) Determine the height of the tree. d) Determine the level of node I.
