The processor's call stack, which is one concrete implementation of a "stack" for one specific purpose: https://en.wikipedia.org/wiki/Call_stack Stack (LIFO collection) implementations exist in various programming languages: https://en.cppreference.com/w/cpp/container/stack https://learn.micros...
Elements may be added or removed in logarithmic time. Heaps are an ideal way to implement priority queues and they are used in the implementation of the Standard Template Library container adaptorpriority_queue Class. The complexity is linear, requiring 3 * (_Last – _First) comparisons. ...
// test.cpp int x, y, r; void f() { x = r; y = 1; } 1. 2. 3. 4. 5. 6. 7. 编译器优化的结果可能导致 y = 1 在 x = r 之前执行完成。首先直接编译此源文件: g++ -S test.cpp 得到相关的汇编代码如下: movl r(%rip), %eax ...

ThePriorityQueueclass implments min heap by default. We apply the same method of implementation for the min-heap as we did for the max-heap. We use the same methods likepeek(),remove(),poll()andcontains()to perform the same operations. ...
Ordinarily we try to maintain as much distance as possible between an ADT and its implementation, but in the case of the Heap, this barrier breaks down a little. The reason is that we are interested in the performance of the operations we implement. For each implementation there are some op...
