👉 Combinators are a fundamental concept in mathematics and computer science that represent operations on lists. They allow for the creation of new lists by combining two or more existing ones, allowing for efficient manipulation of large collections of data.
In combinatorics, there are several types of combinators:
1.
List Combinations
: This is a generalization of combinatorial mathematics where elements in an input list can be repeated multiple times. For example, the combination of 2 apples and 3 oranges
