❌ A. [1, 2] ✅ B. [1] ❌ C. [2] ❌ D. [] ❌ E. The code does not compile ❌ F. None of the above
Explanation: Be careful when autoboxing into Integer. It actually outputs [1]. After adding the two values, the List contains [1, 2]. We then request the element with index 1 be removed. That’s right: index 1. Because there’s already a remove() method that takes an int parameter, Java calls that method rather than autoboxing. If you want to remove the 1, you can write numbers.remove(new Integer(1)) to force wrapper class use.

How Does Bitcoin Mining Work?
Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.
