(c) For the same graph G assume that each edge has a weight obtained by adding the numbers of the two vertices at its ends. For example, 1-2 has weight 3 and 3-5 has weight 8. Give a minimal spanning tree for G .

5. (15 pts) Consider sequences of queue operations, each operation being an enqueue or a dequeue. We assume that the sequences are such that the empty queue exception is never thrown. Let M be a function that, given such a sequence s of queue operations, computes the minimum initial size of the array in which we implement the queue, such that the whole sequence s of operations can be performed without having to increase the size of the array. Give the pseudocode for M in two cases: (a) The simple array implementation which suffers from the problem of drift. (b) The circular array implementation. 6. (20 points) static int foo(char[] a) { for (int j = 2; j < a.length; j = j*j ) a[j] = ’z’; return (a.length * a.length * a.length); } static void bar(char[] b) { for (int i = 1; i < foo(b); i=2*i) b[i]=’z’; } Analyze the worst-case running time of bar(b) as a function of n = b.length and give a Big-Oh bound. 7. (15 pts) (a) Draw a binary search tree with integer keys such that when we traverse the tree in postorder we obtain 3 , 5 , 6 , 4 , 8 , 9 , 7. (b) Draw an AVL binary search tree with integer keys such that when we traverse the tree in
