Challenge Problems
Push your limits with challenges.
Question 1
Analyze the following block of code and identify potential CSE opportunities:
1. a = 5
2. b = a + 2
3. c = 5 + 2
4. d = a + 2
5. e = c + d
💡 Hint: Look for repeated expressions involving 'a'.
Question 2
Take this code sequence that involves unnecessary copies and suggest how copy propagation could help:
1. x = 4
2. y = x
3. z = y + 1
4. x = 10
5. a = x + y
💡 Hint: Consider how replacing 'y' with 'x' can simplify your computations.
