The best resource is straight from the official API: The size, isEmpty, get, set, iterator, and listIterator operations run in constant time. The add operation runs in amortized constant time, that is, adding n elements requires O(n) time. All of the other operations run in linear time (roughly speaking). The constant factor is low compared … Read more
Abstract Data Type(ADT) is a data type, where only behavior is defined but not implementation. Opposite of ADT is Concrete Data Type (CDT), where it contains an implementation of ADT. Examples: Array, List, Map, Queue, Set, Stack, Table, Tree, and Vector are ADTs. Each of these ADTs has many implementations i.e. CDT. The container is … Read more
Defining an ADT In Scala’s “object-functional” model, you define a trait that represents the ADT and all of its parameters. Then for each of your cases, you define either a case class or a case object. Type and value parameters are treated as arguments to the class constructor. Typically, you make the trait sealed so … Read more
Your requirements are exactly those of std::list, except that you’ve decided you don’t like the overhead of node-based allocation. The sane approach is to start at the top and only do as much as you really need: Just use std::list. Benchmark it: is the default allocator really too slow for your purposes? No: you’re done. … Read more

An abstract class is a generalization concept. It is a class you invent to only use as a base class for inheritance but not to instantiate objects from. And abstract datatype (ADT) is not necessarily an OOP concept. It is an older term to describe the concepts of for example Stack and Queue in terms … Read more
Just to address the last part of your question, since that really points out the difference between a list and vector in R: Why do these two expressions not return the same result? x = list(1, 2, 3, 4); x2 = list(1:4) A list can contain any other class as each element. So you can … Read more
