12 Question No. 3 Assume that two senders, A and B, want to send data to C, with the following unique and orthogonal key sequences key Ak101101 for sender A, and key BK101010 for sender B. Sender A wants to send the bit Ad0, sender B wants to sends Bd1. Considering that both signals will be transmitted at the same time using the 2 marks same

Binary Search Tree (14 points) Recall that in a binary search tree, each node is defined as follows. struct node int key node left node right node parent Other data Recall that in a binary search tree, at every node, the key at a node is larger than or equal to the keys in its left subtree, and is smaller or equal to the keys its right

2 Dictionary Abstract Datatype (16 points) Recall that the dictionary abstract data type stores a collection of keys, and supports the operations insert, delete, and search. If the keys are totally ordered, then it can also support FindMin and FindMax. Suppose there are 1000 elements, each of which takes 16 bytes to store. Each element contains a
