HashMap is a data structure that stores key-value pairs and uses hashing to efficiently retrieve values based on keys.
HashMap internally uses an array of linked lists to store key-value pairs.
When a key-value pair is added, the key is hashed to determine the index in the array where it will be stored.
If multiple keys hash to the same index, a linked list is used to handle collisions.
To retrieve a value, the key is hash...

A top view of a binary tree shows the nodes visible when looking at the tree from the top.
The top view of a binary tree is the set of nodes visible when looking at the tree from the top.
Nodes at the same horizontal distance from the root are considered at the same level.
Use a map to store the horizontal distance of each node and only keep the first node encountered at each horizontal distance.
Height of a binary tree is the maximum number of edges on the longest path from the root node to a leaf node.
Height of an empty tree is -1
Height of a tree with only one node is 0
Height of a binary tree can be calculated recursively by finding the height of left and right subtrees and adding 1 to the maximum of the two heights

It will be easier those who are good in C program and mathametics
