right away. Here's an easy way to measure the execution time of each run:func main() { beforeQuadTime := time.Now() quadraticMain() afterQuadTime := time.Since(beforeQuadTime) fmt.Printf("%d\n", afterQuadTime) before3dQuadTime := time.Now() quadratic3dMain() after3dQuatTime := time.Since(before3dQuadTime) fmt.Printf("%d\n", after3dQuatTime)}Side note: Can I say that I am glad that we are a developer community to get them out of the mistakes of the past and to build integrated ti

specified Ncount kernel object, which returns when all objects are notified, and false if any one of them is notified. The role of dwmilliseconds here is exactly the same as the role in WaitForSingleObject (). If the wait times out, the function returns to Wait_timeout.Events can implement thread synchronization operations in different processes, and can easily implement priority comparison wait operations for multiple threads, such as writing multiple WaitForSingleObject to replace waitformult

Unique_ptr• a unique_ptr owns the objects it manages, and unlike shared_ptr, Unique_ptr points to an object that can have only one user . When the unique_ptr is destroyed, the object it points to is also destroyed.• Unlike shared_ptr, no make_shared_ptr-like standard function returns a unqiue_ptr, when a unique_ptr is defined, it needs to be bound to a pointer returned by new, like shared_ptr, Initialization unique_ptr must take the form of direct ini
