Challenge Problems

Push your limits with challenges.

Question 1

In a scenario, you are developing a function that can handle addition of numbers based on their type (signed/unsigned). What precautions should your function take regarding overflow and carry flags?

💡 Hint: Think about logic flows that differentiate signed from unsigned operations.

Question 2

You performed the addition of two large 4-bit numbers, 15 and 1 in unsigned arithmetic. Explain what happens and how it correlates to carry and subsequent calculations.

💡 Hint: What do you know about maximum values in binary dynamic?
