Explanation of UART, SPI, CAN, I2C timing diagrams and frame formats.

• UART: asynchronous serial communication, start and stop bits, baud rate

• SPI: synchronous serial communication, master-slave architecture, clock polarity and phase

• CAN: differential serial communication, arbitration, error detection and correction

• I2C: synchronous serial communication, master-slave architecture, addressing, clock stretching

Classloaders are responsible for loading classes into the JVM at runtime.

• Java has three built-in classloaders: bootstrap, extension, and system.

• Custom classloaders can be created to load classes from non-standard sources.

• Classloaders follow a delegation model, where they first delegate to their parent classloader before attempting to load the class themselves.

• Classloaders can be used for dynamic class loading and hot-s

Detect if two circular linked lists overlap

• Traverse both lists and check if they have the same tail node

• If they have different tail nodes, they do not overlap

• If they have the same tail node, check if they intersect at any point

• Use Floyd's cycle-finding algorithm to detect intersection point
