数据结构 (Data Structure) 数据结构是计算机科学中一个核心概念,它是计算机存储、组织数据的方式。数据结构可以看作是现实世界中数据模型的计算机化表现,而且对于数据结构的选择会直接影响到程序的效率。在C++中,我们有多种数据结构可供选择,如数组(Array)、链表(Linked List)、堆(Heap)、栈(Stack)、队列(Queue)、...

What is Heap Data Structure? Heap is a special tree-based data structure. A binary tree is said to follow a heap data structure if it is a complete binary tree All nodes in the tree follow the property that they are greater than their children i.e. the largest element is at the root...
It contains a pointer to the data itself, the capacity of the vector and the current length of the data. The data array itself is allocated on the heap and is contiguous. The implemented methods are: create insertAtTheEnd insertAt updateAt at size Pros: fast read and write operations, ...
Priority Queue or Heap is an important Data structure that is a queue, but it doesn’t store the elements in FIFO order, but it stores the elements based on Custom Comparator which is attached during Priority Queue creation. If no Custom Comparator is attached, then the elements are stored ...
