Preface As a professional programmer grows, learning data structures and algorithms is crucial. Although many books introduce data structures and algorithms, most of these books are used as university teaching materials and descri

traversal sequence is dabec, the middle-order traversal sequence is debac, and its pre-order traversal sequence is (cedba)18. If abdegcfh and dbgeachf are known as the forward and central traversal of a binary tree, the backward traversal of the binary tree is (dgebhfca)19. If the sequential traversal access order of a binary tree is abdgcefh and the sequential traversal access order is dgbaechf, then the node access order of the sequential traversal is (gdbehfca)20. database protection include

, The approximation of nonlinear problems in numerical analysis and so on. To solve a linear equation group, Gauss-about-extinction (Gauss-jordan elimination) or Kolesky decomposition (Cholesky decomposition) can be used.30, Strukturtensor algorithm -Apply to the field of pattern recognition, for all pixels to find a calculation method to see whether the pixel is in the homogeneous region (homogenous regions), to see if it is an edge, or a vertex.31, merging search algorithm (union-find)-given a

Data structures and algorithms in JavaScript (V): Classic KMP algorithm, data structure and algorithm kmp KMP algorithm and BM algorithm KMP is a classic algorithm for prefix matching and BM suffix matching. It can be seen that the difference between prefix matching and suffix matching is that the comparison sequence i

is too small, may be back overflow, if too large, but also cause a waste of performance, and the list is dynamically allocated, there is no problem. Therefore, generally do not use barrels.6. SummaryA hash table is based on an array, similar to the storage form of a key-value, where the keyword value is mapped to an array subscript by a hash function, which is called a conflict if a keyword is Hashiha to an occupied cell. There are two ways to resolve conflicts: The Open Address method and the

Two-fork Tree Find, INSERT, delete fast (if the tree remains balanced) Delete Algorithm Complex Red-Haishi Find, insert, delete are quick. The tree is always balanced. Algorithmic complexity 2-3-4 Tree Find, insert, delete are quick. The tree is always balanced. Similar trees are useful for disk storage Algorithmic complexity Hash table If the keyword is known, access is extremely fast. Insert Fast D
