Classical algorithm learning-directly select sorting Directly selecting sorting is similar to directly inserting sorting. Data is divided into ordered and unordered areas, the difference is that direct insertion of sorting is to insert the first element of the unordered area directly into the ordered area to form a larger ordered area; directly selecting sorting means selecting the smallest element from the unordered area and putting it at the end of

Classical algorithm learning-exchanging Two integer data The exchange of two numbers is often used in programming. Of course, we can implement them in a common way or in a variety of odd ways. Here we use three more conventional methods. The odd method is not necessary.

Classical C Programming array and programming Array 1. Element swapping Define an integer array num [10], initialize the element values in the array at random, swap the elements at the beginning and end, and output the exchanged array values. [Code] #include 2. Matrix flip Define a two-dimensional array a [3] [4], randomly initialize the element values in the array, and then flip array a to B [4] [3, and output B.

); Move (n-1, B, A, c); Both of these words have changed the order in which the parameters are passed in, and as to why we have to do this, we start by analyzing only two pieces of gold, so as long as you don't get confused by the order of the formal parameters (A,b,c) and the order in which we actually come in, it's good to understand. The output in the green box is the steps to print to the screen, and the Brown line is the return of the recursive execution of each layer, and when we return to

It is more practical to master basic theories and classical design methods than to pursue some so-called new technologies.From the perspective of others' blogs, although I have always had this idea, I have never summed up a sentence. I think there are not many technologies that can be called "innovations" Currently. They mainly deal with complicated and changing needs. In such an environment, it is more important to master basic knowledge. From the op

Similarly, merging two ordered arrays or linked lists is also a classic question in the offer of a sword. The title is described as follows: Enter the list of two ascending orders, merge the two linked lists, and make the nodes in the new list continue to be sorted in ascending order. I'm here to merge the list.Here, there is no need to create a new list, as long as there are three node pointers on the line, the first node pointer Node1 point to the first linked list, the second node pointer Nod

] = k;15 Now I'll focus on the work done by the while loop: It is known that the maximum prefix length is K (k>0) when the previous step is calculated, i.e. p[0] P[K-1]; At this time compare the K-item p[k] and p[q],1 as shown If p[k] equals p[q], then it is simple to jump out of the while loop; The Key! The key is wood! What if the key is not equal??? then we should take advantage of the next[0] we've got. Next[k-1] to beg for p[0] P[K-1] This substring is the large
