Mastering Algorithms for Problem Solving in Java

# Task
An addition chain for an integer $n$ is an increasing sequence of integers that starts with 1 and ends with $n$, such that each entry after the first is the sum of two earlier entries. More formally, the integer sequence $x_0 < x_1 < x_2 < ··· < x_l$ is an addition chain for $n$ if and only if 
- $x_0 = 1$
- $x_l = n$
- For every index $k > 0$, there are indices $i <= j < k$ such that $x_k = x_i + x_j$

The $l$ength of an addition chain is the number of elements minus 1; we don’t bother to count the first entry. For example, $1, 2, 3, 5, 10, 20, 23, 46, 92, 184, 187, 374$ is an addition chain for $374$ of length $11$.

We described a recursive backtracking algorithm to compute a minimum length addition chain for a given positive integer $n$. Don’t analyze or optimize your algorithm’s running time, except to satisfy your own curiosity. A correct algorithm whose running time is exponential in $n$ is sufficient for full credit. Then implement the algorithm to write code in C++.
