Web23. apr 2024 · Let's call the lesser item's position the permutation point. If there are none, that was the last permutation: reverse and return false; then, also beginning from the end, find the first item whose value is superior to that of the permutation point. Swap those two, reverse the range (permutation_point, last) and return true. Web1. apr 2024 · C Programming - Beginner to Advanced; Web Development.
