Data Structures with Generic Types in Java

Solution: Skiplists

Explore the implementation of the findPredNode method in a Java Skiplist to understand how to efficiently search for nodes while avoiding redundant comparisons. This lesson helps you modify the find method to improve performance when duplicate values exist, enhancing your grasp of skiplist data structures.

We'll cover the following...

Task

Complete the task that implements the find(x) method in a Skiplist and sometimes performs redundant comparisons; these occur when x is compared to the same value more than once. They can occur when, for some node, u, u.next[r] = u.next[r − 1]. Modify the find(x) so that these redundant comparisons can be avoided.

Solution

The findPredNode() method in the Skiplist < T > class is a helper function ...
