so its just rearrange the list into random right?
Permutation refers to the arrangement of a set of distinct objects in a particular order. It is a mathematical concept used to calculate the number of possible arrangements of a given set of items.
Permutation takes into account the order of the objects, while combination only considers the selection of objects without regard to their order. For example, 'ABC' and 'CBA' are two different permutations, but the same combination.
One example of a permutation is the arrangement of letters in a word. For instance, the word 'CAT' can be rearranged in six different ways: CAT, ACT, CTA, TAC, ATC, and TCA.
Permutation has many practical applications, such as in cryptography, genetics, and computer science. It is also used in daily life for tasks like arranging seating arrangements at a wedding or creating unique passwords.
The formula for calculating permutations is n!/(n-r)!, where n is the total number of objects and r is the number of objects being arranged. '!' represents the factorial operation, which is the product of all numbers from 1 to the given number.
