II) Now search the right side of above found digit ‘d’ for the smallest digit greater than ‘d’. Next, we swap the "next largest digit" to the front with the iter_swap() statement and then since we know that digit was the next largest, we know that the digits to the right are still in descending order, so to put it in ascending order, we just have to reverse() it. Clearly before entering the main loop it just checks the trivial 0 or 1 element list cases. Stack Overflow for Teams is a private, secure spot for you and

For “534976″, the right side of 4 contains “976”.The smallest digit greater than 4 is 6.. III) Swap the above found two digits, we get 536974 in above example. We only change the position of a "digit" when everything to the right is in descending order because if it isn't in descending order then there are still more permutations to go (ie we can "increase" the permutation by a smaller amount). Note : (i)Cnn=1 and C0n =1 (ii)Crn=C(n-r)n, Examples : (i) C411=11×10×9×84×3×2×1=330 (ii)C1316=C(16-13)16=C316=560.
