# Trace2 Example
# Perform variable trace and predict output. 

a = 2
b = 5
if a + b <= 3:
    c = -1

elif a + b <= 6:
    c = 0

else:
    c = 1

print(f"Output: {a + b} {c}")

# Trace:   a    b    c   Output:  Output: 7 1
#        ----+----+---- 
#          2 |  5 |  1
#         
#        Neither a + b <= 3 or z + b <= 6 is true
#        so perform c = 1.
