Pick one and press Start, then click Next › to step through it.
Watch for
The search hopping across the top lanes and only dropping to the bottom near the target — that's the log-N shortcut.
More about this scenario
You'll learn
How randomized 'express lanes' give a skip list O(log N) search without the complexity of balancing a tree.
How it runs
Each INSERT flips coins to decide how many express lanes a node joins. A SEARCH starts at the top lane, skips forward until it would overshoot, drops a level, and repeats — most nodes are skipped entirely.
