Queue List Stack Can’t traverse a tree in order without recursion The data structure that keeps track of activation records during the execution of a program Run-time queue Run-time stack Linked list Heap Which of the following statements could describe the base case of a recursive algorithm? F(x) = x – F(x – 1) If the array length is 100, do nothing All parameters are integers F(0) = 27 B and D above Int Func(/*in*/int n) { If (n == 5) Return 5; Else Return 2 * Func (n+1); } What is the value of the expression Func (2)? The three-question testing method is based on what computing technique?
