(3) public static void test_b(int n) { if (n>0) test_b(n-2); System.out.println(n + " "); Consider the following method: What is printed by the call test_b(4)? A. 0 2 4 B. 0 2 C. 2 4 D. 4 2 E. 4 20 3 (4) What is the efficacy class of +? n 3 A: ©(1) B: O (log n) C: O (n) D: O (n log n) E: Θ n)

What is the value of x when i = 4? #include int main (void) { int x = for (int i = 0; i <= 4; ++i) { X = X + i; } printf("%d %d", i, x); return 0; }

True or False: (a) In a debugger, we can choose whether to step into, step over, or step out of a particular method call. (b) Debuggers, tests, and println() statements are all legitimate ways to help us find errors in our code.

public class Test { } public static void main(String[] args){ int a = 10; System.out.println(a*a--); }

Java true or false: The method public boolean simpleMethod() { return true; } is a valid mutator?
