We can first put n−1n−1 elements to an array, and then insert the negative of the sum of these n−1n−1 elements. Since we can only use elements within range [−n,n][−n,n], the sum of the n−1n−1 elements has to be within that range too. The strategy for ...

maxLevel: The maximum level of the skip list (controls the space vs. time trade-off). p: The probability factor used to determine the level of new nodes (usually set to 0.5). Methods: Insert(value T): Inserts a value into the skip list. Delete(value T): Deletes a value from the...

The Make-Set is called whenever a new vertex is generated, which corresponds to the insert operation of a regular data structure. When a vertex is generated, it is unconnected and therefore a tree of its own with just one element that points to itself. The rank of a node approximates ...
