Heap data structure is a balanced binary tree data structure where the child node is placed in comparison to the root node and then arranged accordingly.

partition used by the heap. By default, a heap has a single partition. When a heap has multiple partitions, each partition has a heap structure that contains the data for that specific partition. For example, if a heap has four partitions, there are four heap structures; one in each ...
Data in the stack is stored in contiguous blocks due to its linear structure Heap stores elements in a random manner due to its hierarchical structure Allocation and deallocation in the stack are automatically managed Heap memory requires manual management Stack can be implemented using array, linked...
