For this question, recall the definition of a B-tree: A B-tree of order m is a multiway search tree where the root has at least two subtrees unless it is a leaf: each nonroot and each nonleaf node holds k - 1 keys and k references to subtrees, where [m/2] lessthanorequalto k lessthanorequalto m: each leaf node holds k - 1 keys where [m/2] lessthanorequalto k lessthanorequalto m: and all leaves are on the same level. a. Describe one advantage of using multiway search trees rather than binary search trees. Write no more than three lines. b. Insert, the values 1, 2, 3, 4, 5, 6, 7, 8 into an empty 2 3 tree (i.e. a multiway tree where m = 3). c. Recall that for a 2 3 tree a node in the tree is an array of two elements: below is the definition from Drozdek. public class BTreeNode { int m = 3: boolean leaf = true: int keyTally = 1: int keys[] = new int[m-1]: BTreeNode references[] = new BTreeNode[m]: BTreeNode(int key) { keys[0] = key: for (int i = 0: i
