If we maintain a reference to the position of the leftmost node of a binary search tree, then operation firstEntry can be performed in O(1) time. Describe how the implementation of the other map...
Describe a modification to the binary search-tree data structure that would support the following two index-based operations for a sorted map in O(h) time, where h is the height of the...
1. Draw a splay tree, T1, together with the sequence of updates that produced it, and a red-black tree, T2, on the same set of ten entries, such that a preorder traversal of T1 would be the same as...
1. The boolean indicator used to mark nodes in a red-black tree as being “red” or “black” is not strictly needed when we have distinct keys. Describe a scheme for implementing a red-black tree...
