This is a Combinatorics Problem
Consider the problem of finding the number of ways to distribute
7 identical pieces of candy to 3 children so that no
child gets more than 4 pieces. Except Stanley (one of the 3
children) has had too much candy already, so he’s only
allowed up to 2 pieces. Write a generating function & use your
generating function to solve this problem.

Combinatorics:
6. A mathematician picks and integer i from the set
{1,2,3,...,15} and a computer scientist tries to find the number by
asking questions of the form: Is i<x, i>x, or i=x? Show that
the number can always be found using three questions
