--; Swap (Num[i], num[j]);2. Since j is the first element greater than I, after the Exchange, II starts to the end, still satisfies the descending order, the direct reverse gets the increment arrangement. Note that the flip starts from II.After the exchange, it is still in descending order. Reverse (Num.begin () + II, Num.end ());3. Simple memory steps
Looking forward from the end of the end to two adjacent elements, both satisfying I

process is more standardized, the amount of manual encoding is reduced, and the encoding efficiency is improved. At the same time, when data is updated, sometimes the component is not required, but it also needs to be re-drawn, which affects the efficiency. Generally, they are used only when building complex projects with multiple interactions and data streams.
