Recall that a skip list is a linked list with multiple levels. When an item is added, the followingprocedure is used to potentially place the item in multiple levels:1. Find where to insert the element at the lowest level.2. Insert the item at the current level.3. Flip a fair coin:i. If the result is heads, move up one level and continue from step 2.ii. Otherwise stop. Suppose we addnitems to an initially empty skip list (and delete none of them). Let randomvariableZibe the number of items at leveli(where level 0 is the lowest level), and let randomvariablehbe theheightof the skip list, i. e., the highest non-empty level.
