1. Basic concepts of value-added business management 1) changes in value-added business management The value-added business chain tends to be open: from the initial technology-centric to user needs and market-centric, the role of operators is constantly changing. The operator has changed its operating model from self-developed business to providing business capabilities and managing networks, CP/SP and third-party services. Operators' value-added

Spoj_2798 If you use link-cut-tree to write data, you only need to maintain the col (node color) and sum (number of black nodes in the subtree) labels. During the dyeing process, the corresponding node splay is added to the root node and then modified. The access (v) operation is performed first during the query, and then the root of the splay is searched recursively, if the sum value of the root node is 0,-1 is output. # Include # Include String .

It can be said that depending on the interface, different results are rendered.For ES6 before the implementation of inheritance, polymorphism, encapsulation principle, mainly around the prototype, prototype chain call to achieve, although the current ES6 can be very g

operation is called unlocking. a thread that has locked a mutex lock but has not yet unlocked is called occupying the mutex lock. 3. Use semaphores to schedule shared resources In this case, a thread uses a semaphore to notify another thread, and a condition in the program State is already true. Such as producer-Consumer issues.
