Permutation
|
Functionality and example
A Permutation (from the latin word permutare "to (inter)change") means a change of the sequence from elements of a string. In mathematical terms a permutation is a bijective self-mapping of a usually finite set. Colloquially the term is also used as a synoynm for "Placement".
A Permutation of the string "ABC" results in "ABC ACB BAC BCA CAB CBA".
A special case of Permutations are Anagrams, where the Permutation result of a known word is again a known word. For example the word "EVIL" is an anagram of "VILE".
