Consider the following recursive method. public static void stars(int num) { if (num == 1) { return; }   stars(num – 1);   for (int i = 0; i < num; i++) { System.out.print("*"); } System.out.println(); } What is printed as a result of the method call stars(5) ?   A ***** B ** *** **** ***** C * ** *** **** ***** D ***** **** *** ** E ***** **** *** ** *

The bark method below is intended to print the string “woof” a total of num times. public static void bark(int num) { if (num > 0) { System.out.println(“woof”); /* missing code */ } } Which of the following can be used to replace /* missing code */ so that the call bark(5) will cause “woof” to be printed five times?

In a symmetric encryption scheme built using the ECB mode of operation, the key generation algorithm is used to randomly pick a key from the keyspace for every new block of the message that has to be encrypted 

Since the encryption scheme is publicly available, in an IND-CPA experiment, an attacker is able to compute ciphertexts for their chosen message without consulting the oracle.
