Recursion Question 5. In the following question, you will be asked to program the following using recursion. If you have an iterative solution, you may use it, but the most you can get for the question will be half credit. (5) points) Consider the following mathematical function h which operates on integers. (1, if n < 2 h(n) = n(n-1) +n if n > 2 and n is even han -2) +2*n if n > 2 and n is odd In Java, use recursion to write a method h which takes as input an int n and returns h (n). public static int h(int n) {

1. Describe what is meant by a library routine and suggest reasons why using su h a routine is of benefit to a programmer

• An analysis of a compound shows that it contains 19.8 g. of Carbon, 2.50 g. of Hydrogen, and 11.6 g of Nitrogen. What is the percentage composition of C, H, O?
