这里的next_permutation的实现思想跟第二部分中全排列的非递归实现的思想一样. 下面给出cppreference.com 提供的一种next_permutation的实现方法: template<classBidirIt>boolnext_permutation(BidirIt first, BidirIt last){if(first == last)returnfalse; BidirIt i = last;if(first == --i)returnfalse;while(...

Next, we swap the "next largest digit" to the front with theiter_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 toreverse()it. boolmy_next_...
