Permutation -- from Wolfram MathWorld

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}. WebPermutation is a vector / list that stores the actual permutation. Each function call tries to append a new element to the permutation if an element at position within the set has not been included. If the size of the permutations vector equals the size of the set containing the elements, a permutation has been found. WebA permutation is the number of ways by which we can arrange a set or an object in a definite order. The mathematical formula to calculate a permutation is given below: The formula … line on sight
