Answer:
K1 ⊕ K2 = 9
Explanation:
Since 5 ⊕ K = 12, K must be 5 ⊕ 12 = 9.
But there are supposedly two encryptionkeys, we cannot know their individual value, only that K1 ⊕ K2 = 9.
That makes this a bit weird question.
#4 is true
We use pseudocode to help us understand code.
#5 is false
Strings are surrounded by quotes, integers are not.
#6 is 100.
Integers are numbers with no decimal places.
