👉 A literator is a set of rules that define how to use an iterator in a programming language. An iterator is a sequence of elements from a data structure, such as a list or a string, and it allows you to access the next element in the sequence without having to go through all the elements one by one. In other words, a literator defines the order in which elements are added to an iterator. It can be used to ensure that the iterator is always treated like a regular sequence
