as expected but it does two swaps for each pass. = std:: distance (first2, last2) no applications of the predicate are made. I haven’t been able to compute the permutations for 11 elements with it as it runs out of memory… after about 20 minutes.

What if we generated permutations just by taking the existing permutation and modifying it slightly? In this article, we are going to see what is the STL function next_permutation() and what's the use of it and how to use it in a program? If you’re curious, you should try out the Steinhaus–Johnson–Trotter algorithm, which implements a pattern that 17th-century bell-ringers used. Step 1 : Find the all possible combination of sequence of decimals using an algorithm like heap's algorithm in O(N!) The lexicographically next permutation is basically the greater permutation. I implemented this algorithm iteratively, using a series of while loops. The replacement must be in place and use only constant extra memory.. Finally, it adds the remaining individual element back into the sub-problem’s solution. Find the largest k such that a[k]
