The above method requires careful programming. In fact, there can be more aha algorithms. To convert AB to Ba, you can perform the following operations: first, reverse (A), reverse (B), and finally r

The first section, depth and breadth first refers to whatFor the traversal of the graph.The main idea of depth-first traversal is to traverse one of the branches of the graph until the end, then back up, and then do the same traversal along another line until all the vertices have been accessed.The main idea of breadth-first traversal is to first access all of its adjacent vertices with an unused vertex, and then to each adjacent vertex, and then access their adjacent, inaccessible vertices unti

This article begins with a discussion of some simple concepts and algorithms for the "tree".Tree is a basic data structure, the reason is called the tree is derived from the bionic-branch bifurcation structure or the structure of the root fork, it is very good to express the logical relationship between the nodes, it is also a very important structure of graph theory. From the point of view of its name, we find that much of the growth of scientific thinking stems from a keen observation of natur

Today began the study of the "AHA algorithm" book. Generally speaking, this book is the algorithm of the small petition, the language is very popular, the introduction of the algorithm is relatively simple, now back to see the simple things will seem to waste time? Otherwise, I recently feel that the competition is not the ultimate way, the direction of learning is also changed to book as the object ("Specific mathematics" a column of the establishmen

Quick sorting of Aha AlgorithmsEfficiency issues The Bubble Sorting mentioned above can be said to be our first real algorithm, it solves the problem that bucket sorting occupies a large amount of space (because bucket sorting requires a specified memory according to the number of sorted data), but Bubble Sorting sacrifices a lot of efficiency, suppose we want to sort the number of 0.1 billion, because the time complexity of Bucket sorting is O (M + N

;VK, VK->VJ is also based on E[i][k], e[k][j], so we actually enumerate a series of relatively optimal cases, Then we find the current optimal solutions in these relative optimal solutions, and this is the place that the dynamic programming idea embodies.Essentially, the algorithm is a clever combination of enumeration and dynamic programming.#include using namespacestd;intMain () {inte[Ten][Ten], K, I, J, N, M, t1,t2,t3; intINF =9999999; scanf ("%d%d",n,m); for(i =1; i) for(j =1; j)

".notes:fast sorting is faster because each exchange is a jump-through compared to a bubbling sort. Every time I sort.sets a datum point that places a number less than or equal to the datum point to the left of the Datum point, and a number greater than or equal to the datum pointto the right of the datum point. This will not be the same as bubble sort in each exchange, only between the number of adjacentExchange , the distance is much greater. Therefore, the total comparison and the number of e

correctly returned, it is important to understand.About efficiencyfast sorting is faster than the bubbling sort of each swap location is a jumping, each sorting set a base number, the less than the base number on the left, greater than the number of the base to the right, so that it does not have to be compared with the number of adjacent to a bubble sort at a time to compare the exchange location so the matter, The number of comparisons is much less, which increases efficiency. So the worst bu

Section 3 heap sorting Create a heap of n elements. First, encode the N nodes from 1 to n in the top-down and left-right mode, in this way, N nodes can be converted into a Complete Binary Tree. Then, from the last non-leaf node (node number is n/2)
