Backtracking: P5 (15pt): An addition chain for an integer n is

Backtracking: P5 (15pt): 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 1, is an addition chain for 374 of length 11. Describe 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. (Hint: This problem is a lot more like N-Queens than text segmentation.
