WebA permutation also called an “arrangement number” or “order,” is a rearrangement of the elements of an array, arr into a one-to-one correspondence with arr itself. An array of length n has n! Permutation. Let say we have arr [] = {1,2,3} All possible permutation of the given array are : {3,1,2}, {3,2,1}, {1,2,3}, {1,3,2} , {2,1,3}, {2,3,1}. We can also apply the randomized algorithm for determining the permutation of numbers. It is used if the value of n is big. The algorithm generates the permutations by shuffling the array. For shuffling, the Java Collections class provides the shuffle() method. The shuffle() method randomly permutates the specified … See more In mathematics, the permutation is a method or technique in which we can determine the possible arrangements in a set.

For example, there are six permutations of the set {1,2,3}, namely (1,2,3), (1,3,2), (2,1,3), (2,3,1), (3,1,2), and (3,2,1).
