a) An m-ary tree is a tree in which every node has at most m children. Consider a special m-ary tree in which a node either has exactly m children or no children. What is the minimum number of nodes ina special m-ary tree of height ? (A single node tree has height 0). Show your work, and show how your answer works out correctly by drawing a special tree with h 3 and m3 (and any set of values at the nodes)
