Permutation with arrays in c++

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}.
