First, the topic requirements:Merging K ordered linked lists into an ordered listSecond, the realization method:Method one: Using the minimum heap methodUse a minimum heap of size K (implemented with priority queue + custom Descending) (priority queue is the Big top heap, team head element is the largest, custom to descending, it becomes the small top heap, the team head element is the smallest), first put K list of head node in the heap, each fetch heap top element, It then joins the next node

Merge sort (Merge-sort) is an efficient sorting algorithm based on merging operation, which is a very typical application of divide-and-conquer method (Divide and Conquer). The ordered Subsequence is merged to obtain a fully ordered sequence, i.e., the order of each subsequence is ordered, and then the sequence of sub-sequences is ordered. If you combine two ordered tables into an ordered table called two-way mergeCode:void Mergearray (struct sq_list *v, int first, int mid, int last, int temp[])

time. Then, the data on both sides of the K, and then the process is divided into the above, until no further grouping. Note: The first time quick sort does not directly get the final result, only the number smaller than K and K is divided into the two sides of K. To get the final result, you need to perform this step again on an array of subscript 22 edges, and then decompose the array until the array is no longer decomposed (only one data) to get the correct result. The code is as follows:vo

Select the overlay mode and add a layer of projection. 8. select a wooden texture image to reduce the saturation and stack it on the top of the Wood Group.

original ASP, and are not related to IIS. The IIS pipeline is interpreted using a module. These modules, which were originally part of ASP., are now an integral part of the IIS pipeline. The IIS pipeline provides more than 20 events that developers can use to extend the functionality of the Web server. In fact, we can replace modules in IIS 7.0 with custom modules by creating custom modules, updating applicationhost.config at the same time, using only custom modules, without using the built-in

Crocodile rule (Alligator Principle)One of the technical rules of economic trading, also known as the "crocodile effect", is that if a crocodile bites your foot, if you try to break out of your foot with your hand, the crocodile will bite your feet and hands at the same time, and the more you struggle, the more you will be bitten. Natural weakness of human nature, will affect our operation, a big loss, enough to lose 99 of the previous profit, so strict adherence to the law of Stop loss is to en
