Challenge: Backtracking
Explore how to apply recursive backtracking to find minimum length addition chains in C++. Learn to implement and understand the algorithm that builds a chain of sums leading to your target number. This lesson helps you sharpen problem-solving skills by coding a backtracking solution that explores combinations systematically.

Task
An addition chain for an integer is an increasing sequence of integers that starts with and ends with , such that each entry after the first is the sum of two earlier entries. More formally, the integer sequence ...
