//Instructions:
//Write a C# program that simulates a team hiking through a forest at night.
//The team encounters a series of narrow bridges along the way. At each bridge they may meet additional hikers who need their help to cross the bridge.
//The narrow bridge can only hold two people at a time.
//They have one torch and because it's night, the torch has to be used when crossing the bridge.
//Each hiker can cross the bridge at different speeds. When two hikers cross the bridge together, they must move at the slower person's pace.
//Determine the fastest time that the hikers can cross each bridge and the total time for all crossings.
//The input to the program will be a yaml file that describes the speeds of each person, the bridges encountered, their length,
//and the additional hikers encountered along the way.
//Your solution should assume any number of people and bridges can be provided as inputs.
//Demonstrate the operation of your program using the following inputs:
//the hikers cross 3 bridges, at the first bridge(100 ft long)
//4 hikers cross(hiker A can cross at 100 ft/minute, B at 50 ft/minute, C at 20 ft/minute, and D at 10 ft/minute),
//at the second bridge(250 ft long) an additional hiker crosses with the team(E at 2.5 ft / minute),
//and finally at the last bridge(150 ft long) two hikers are encountered(F at 25 ft / minute and G at 15 ft / minute).
//You will be judged on the following:
//Strategy(s) - there are several ways to solve the problem, you can provide more than one. The goal is to show us how you think.
//Architecture and design - we want to see how well you architect and design solutions to complex problems.
//Testing - we want to see how you approach testing of the solution.
//Standards and best practices.
//Explanation - as a C# thought leader in the organization you will be working with and mentoring other engineers. How well you can describe and explain your solution is very important.
//Please provide a link to your git repo such as github or bitbucket with your solution.
//I'm building the Adventure ata from the yaml file with a builder pattern.
string inputFilePath = "./Data/Input.yaml";
AdventureDataBuilder adventureDataBuilder = new AdventureDataBuilder(inputFilePath);
adventureDataBuilder.Build();
Adventure currentAdventure = new Adventure(adventureDataBuilder.GetAdventureData());
//I'm using the observer pattern to fetch information about the adventure to log to the console to track progress.

currentAdventure.Attach(adventureObserver);
