Explanation / Answer

Question 1:

Answer: D. col1 = [1, 9, 3, 7, 5]

In this case, As per logic it will return max value as 5 which is wrong.

Question 2:

Answer: D x.eqauls(y) == false

x.compareTo(y) value is 1 means x and y are not same. if both are same then x.compareTo(y) will return 0.

So D option is the correct answer to say both are not same.
