WebApr 23, 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. WebC++ Algorithm next_permutation () function is used to reorder the elements in the range [first, last) into the next lexicographically greater permutation. A permutation is specified as each of several possible ways in which a set or number of things can be ordered or arranged. It is denoted as N! where N = number of elements in the range.
