Lena is designing a helper for the internal roadmap tool that calculates the most efficient way to navigate through a sequence of project stages. Each stage provides a certain amount of momentum, allowing the team to skip over several upcoming steps at once. Eva reviewed the proposal and asked Lena to ensure the tool always finds the fewest number of moves needed to reach the final objective. For example, if the first stage allows a jump of up to two steps and the second stage allows a jump of up to three, the team could reach their goal in only two moves by landing on that second stage first.
