flatMap in Java 8 is a method used to transform each element of a stream into another stream and then concatenate all the streams into a single stream.
flatMap is used to flatten nested collections in streams.
It is commonly used with streams of collections or arrays.
Example: List> list = Arrays.asList(Arrays.asList(1, 2), Arrays.asList(3, 4)); list.stream().flatMap(Collection::stream).forEach(System.out::println);
I applied via Company Website and was interviewed in Jun 2023. There were 3 interview rounds.
Medium level Strings and Array questions
LCA of a node in BST is the lowest common ancestor of two nodes in a binary search tree.
Traverse the BST from the root node to find the LCA of the given nodes.
Compare the values of the nodes with the current node to determine the LCA.
If one node is on the left subtree and the other is on the right subtree, the current node is the LCA.
Optimize the solution by using efficient data structures and algorithms.
Use HashMap instead of ArrayList for faster lookup
Implement caching to store previously calculated results
Consider using multithreading for parallel processing

I applied via LinkedIn and was interviewed in Feb 2023. There were 2 interview rounds.
HashMap is a data structure that stores key-value pairs and uses hashing to retrieve values.
HashMap uses an array of buckets to store key-value pairs
The hash code of the key is used to determine the index of the bucket
If multiple keys have the same hash code, they are stored in a linked list within the bucket
HashMap allows null keys and values
HashMap is not thread-safe and requires synchronization for concurrent access

Collect the result using collect(Collectors.toList())
Static methods can be accessed without creating an instance of the class, while final keyword makes the method unchangeable.
Static methods belong to the class itself, not to any specific instance
Final keyword ensures that the method cannot be overridden in subclasses
Static methods are commonly used for utility methods that do not require access to instance variables
Example: Math class in Java has static methods like Ma
The @RestController annotation is used to define RESTful web services while @Controller annotation is used to define MVC controller.
