can be used across processes (via Openmutex,openevent,opensemaphore). However, why only the mutex can solve the "abandonment" situation, please see the second multi-threaded 15th key section, events, mutual exclusion, signal volume of "abandonment" problem. Hehe ^_^, this series used six articles to explain the above three tables, if the reader can easily write this table and can explain the use of the function, then the multi-threaded synchronization mutex problem also has a good foundation.Se

obtained. and analyze the complexity of time.This problem is similar to leetcode inside about the problem of the connector, it needs to be clear that the height may be 0, the longest length of the rectangle is not necessarily the largest rectangle, but also need to consider a high height, but shorter length of the rectangle. The height of the largest rectangle in [5,4,3,2,4,5,0,7,8,4,6] is a rectangle consisting of [7,8,4,6], with an area of 16.2, the largest sub-rectangle on the ring surface"A
