Answer:
To figure out which areas will be affected by the flood, you'll need to follow certain rules and guidelines. Here's how you can approach the problem:
1. Read the file: Design a class that reads the file and retrieves the necessary information like the map dimensions, start position, and water amount. This class should have methods to validate the file and check if it meets the specified requirements (e.g., file existence, valid start position, etc.).
2. Traverse the map: Design another class that will traverse the map based on the flooding rules. This class should have member variables to keep track of the current position and the remaining water amount. It should also have methods to check for valid moves and update the map accordingly.
3. Detect backtracking: When you reach a dead end on the map, you'll need to backtrack. To do this, you'll need to update variables, objects, or arrays that keep track of the previous positions and the paths taken. These variables will allow you to backtrack to a previous valid position and continue exploring other possible paths.
4. Detect flooding and water shortage: While traversing the map, you should check for two conditions:
a. If no more spaces can be flooded: If you find that there are no more low ground spaces adjacent to the current position, the flooding stops.
b. If you run out of water: If the remaining water amount becomes zero, the flooding stops.
5. Flood the map: Using recursion, start the flood at the specified start position. Move orthogonally (up, right, down, or left) to the adjacent spaces and check if they meet the flooding rules. If a space can be flooded, mark it with a '~' symbol to indicate it has been flooded. Continue this process until the flooding stops due to either running out of water or no more spaces to flood.
6. Output the flood path: After the flood is complete, print the updated map to the screen. The flooded spaces will be marked with '~'. Additionally, indicate whether the flood ran out of water or if it completely flooded the accessible area.
Remember to consider all the given rules, such as not crossing high ground, checking for valid moves in a specific order, and validating the start position. By following these steps, you should be able to accurately flood the map and provide the desired output.
