To index the skip list and find the i'th value, traverse the skip list while counting down the widths of each traversed link. Descend a level whenever the upcoming width would be too large. For example, to find the node in the fifth position (Node 5), traverse a link of width 1 at the top level.
In a skip list, one can finger search for x from a node containing the element y by simply continuing the search from this point. Note that if x < y, then search proceeds backwards, and if x > y, then search proceeds forwards. The backwards case is symmetric to normal search in a skip list, but the forward case is actually more complex.
A list may contain the same value more than once, and each occurrence is considered a distinct item. A singly-linked list structure, implementing a list with three integer elements. The term list is also used for several concrete data structures that can be used to implement abstract lists, especially linked lists and arrays.
When searching the trees for nodes overlapping with a given interval, you can immediately skip: all nodes to the right of nodes whose low value is past the end of the given interval. all nodes that have their maximum high value below the start of the given interval.
<initializer_list> Added in C++11. Provides initializer list support. <limits> Provides the class template std::numeric_limits, used for describing properties of fundamental numeric types. <new> Provides operators new and delete and other functions and types composing the fundamentals of C++ memory management. <source_location> Added in C++20.
I've actually tested skip lists extensively and can tell you that in C++ at least, skip lists are exactly on par and occasionally faster with the map template for speed and use about the same amount of memory. Skip lists memory usage and speed can be tweaked according to your need and can reproduce a map quite easily.
In the C++ programming language, argument-dependent lookup (ADL), or argument-dependent name lookup, [1] applies to the lookup of an unqualified function name depending on the types of the arguments given to the function call. This behavior is also known as Koenig lookup, as it is often attributed to Andrew Koenig, though he is not its inventor ...
Searching for a value in a trie is guided by the characters in the search string key, as each node in the trie contains a corresponding link to each possible character in the given string. Thus, following the string within the trie yields the associated value for the given string key.
