Bluetooth and Wi-Fi performance testing involves various methodologies to ensure reliability, speed, and range in real-world scenarios.
Conduct throughput tests to measure data transfer rates under different conditions.
Perform range tests to determine the effective coverage area of Bluetooth and Wi-Fi signals.

Encoding RLC status PDU involves understanding the RLC protocol and its status reporting mechanisms.
RLC (Radio Link Control) is part of the LTE protocol stack.
Status PDU indicates the status of data transmission (e.g., successful, failed).
Encoding involves creating a binary representation of the status information.
Example: A status PDU may include information about the number of successfully received packets.
RLC u...
Count the number of connected islands in a graph
Use Depth First Search (DFS) or Breadth First Search (BFS) to traverse the graph and mark visited nodes
Keep track of the number of islands encountered during traversal
An island is a group of connected 1s in a 2D grid, where '1' represents land and '0' represents water
Understanding hashcode and equals methods is crucial for object comparison and storage in hash-based collections.
The hashCode() method returns an integer representation of an object, used in hash tables.
The equals() method checks if two objects are logically equivalent.
If two objects are equal (equals() returns true), they must have the same hash code (hashCode() returns the same value).
Example: In a custom class,...
Designing a thread-safe singleton class
Use double-checked locking to ensure thread safety
Make the constructor private to prevent direct instantiation
Provide a static method to access the singleton instance
Use synchronized keyword or locks to handle concurrent access
Consider lazy initialization or eager initialization based on requirements
Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.
Identify the primary key of the table
Eliminate repeating groups and create separate tables for them
Ensure each table has a single theme or subject
Create relationships between tables using foreign keys
Ensure data is consistent and follows a standard format
Virtual function is a function in base class that is overridden in derived class.
Virtual function allows polymorphism in C++.
It is declared in base class with virtual keyword.
It is overridden in derived class with same signature.
It is called based on the object type at runtime.
Example: virtual void display() = 0; // pure virtual function
To move the cursor 5 characters ahead of current position in an opened file.
Use fseek() function to move the cursor to the desired position.
Pass the current position and offset to fseek() function.
Use SEEK_CUR as the reference point for the offset.
Answering which statement about a binary heap is false.
A binary heap is a complete binary tree where the parent node is always greater or smaller than its children.
A binary heap can be represented as an array.
A binary heap can be used to implement priority queues.
A binary heap can only be a max heap and not a min heap.
Circular buffer program with producer and consumer scenario, detecting overflow and stopping producer.
Implement a circular buffer with a fixed size and two pointers for producer and consumer
Use semaphores to synchronize access to the buffer
When the buffer is full, stop the producer until the consumer reads from the buffer
When the buffer is empty, stop the consumer until the producer writes to the buffer
Use mutex l...
