What is permutation?
When the order of the arrangements counts, a permutation is a mathematical technique that establishes the total number of alternative arrangements in a collection. Choosing only a few items from a collection of options in a specific sequence is a common task in arithmetic problems.
A permutation of a set exists, loosely articulating, an arrangement of its members into a sequence or linear order, or if the set exists already contained, a rearrangement of its elements.
