Just learning PHP, the master can give a use of PHP to implement the linked list and two-tree code

The traversal of a treeThese three kinds of traversal methods are actually very simple, for example: a / b cThis is an example of how these three are traversed.struct treenode;typedef treenode* node;typedef int eletype;struct treenode{ Node lchild; Node Rchild; Eletype data;};First Order traversalThe first sequence traversal, that is, from the top to the bottom, from left to right, encountered a traversal, the above example traversal sequence is:a b cThe recursive code is

In Matlab, there are a variety of classifier training functions, such as "FITCSVM", but also a graphical interface of the classification of Learning Toolbox, which contains SVM, decision tree, KNN and other types of classifiers, the use of very convenient. Then let's talk about how to use it. Start: Click "Application", find "classification learner" icon in the Panel click to Start, also can enter "Classifi
