C++ DATA structure Exercise 6.1. Prove that a binary tree having n ≥ 1 nodes has n − 1 edges.
Problem 2 (8 pts): Structural Induction In a binary tree, a full node is a node with two children. Using structural induction, prove that the number of full nodes plus one is equal to the number of leaves in a binary tree (even if the tree itself is not necessarily full, i.e. some nodes may not be full)
induction question, thanks. (15 points) Prove by induction that for an odd k > 1, the number 2n+2 divides k2" – 1 for all every positive integer n.

Induction proofs. a. Prove by induction: n sum i^3 = [n^2][(n+1)^2]/4 i=1 Note: sum is intended to be the summation symbol, and ^ means what follows is an exponent b. Prove by induction: n^2 - n is even for any n >= 1 10 points 6) Given: T(1) = 2 T(N) = T(N-1) + 3, N>1 What would the value of T(10) be? 7) For the problem above, is there a formula I could use that could directly calculate T(N)?...
