WebIn C++, a hash map is a data structure that contains a collection of unique elements in the form of key-value pairs. Elements of a hash map are identified by key values, while the mapped values are the content associated with the keys. Each element of a map or unordered_map is an object of type pair.

WebMathematically, it can be defined as: A [Parent (i)] <= A [i] Let's understand the min-heap through an example. In the above figure, 11 is the root node, and the value of the root node is less than the value of all the other nodes (left child or a right child). Max Heap: The value of the parent node is greater than or equal to its children. Or WebHash tables are O (1) average and amortized case complexity, however it suffers from O (n) worst case time complexity. [And I think this is where your confusion is] Hash tables suffer from O (n) worst time complexity due to two reasons: If too many elements were hashed into the same key: looking inside this key may take O (n) time.
