As soon as a single node was added to the middle of the lists, all the heights following it would need to be modified. But we can relax this requirement to achieve an efficient data structure.

TīmeklisSkip List Insertion Deciding nodes level while Insertion: Each element in the list is represented by a node, the level of the node is chosen randomly while insertion in the list. Level does not depend on the number of elements in the node. The level for node is decided by the following algorithm: twitter sbbTīmeklis2024. gada 16. apr. · dhayden (5782) The code works for me. I see that level () returns 1 for the bottom level, not 0. That might be throwing off some other code.
