Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If a program consists of moving a decimal number 25 into the Accumulator, adding together the contents of the Accumulator and a large number kept in Register B, what will be the expected flags if Register B contains 30?

💡 Hint: Analyze how larger numbers impact the Accumulator during operations.
