1) Why Reinforcement Learning? Describe the main elements of a Reinforcement Learning system.
Answer:
Reinforcement Learning (RL) is important because it enables machines to learn optimal behaviors through interaction with their
environment, without needing labeled input/output pairs. It's especially useful in scenarios where the best actions are not immediately

Java is well-known for its ability to run on any device or platform thanks to the "Write Once, Run Anywhere" (WORA) philosophy. This is made possible because Java code is compiled into bytecode that runs on the Java Virtual Machine (JVM) instead of being compiled directly into machine code specific to any system. How Java achieves portability:
Java Compiler and Bytecode: When you write Java code, it’s compiled into bytecode, which is platform-independent. This bytecode is stored in .

Debt management
Debt management is a strategic approach to handling and repaying debts in an organized manner.
