Implement a Java program that verifies the validity of skyscraper puzzles. The program should include a Skyscraper class with private variables representing the board configuration and the following public methods:

• public boolean verifyPlacement() – returns true if each row and column contains each number exactly once; otherwise false.
• public void loadPuzzle() – reads a puzzle from standard input and updates instance variables accordingly.
• public void print() – outputs the puzzle in the specified format.
• public void printWithVisibility() – outputs the puzzle along with visibility scores.

The main method should load a puzzle, verify its placement, and print the puzzle with visibility if valid.

The input format: first line contains the dimension (DIM); the next DIM lines each contain DIM integers representing the puzzle layout; remaining lines are ignored. The output format: print the puzzle and visibility scores as specified.

You should also include helper methods as needed, all declared private, and ensure all class variables are private.

The skyscraper puzzle is a classic logic game where players arrange buildings of different heights within a grid so that certain visibility criteria from the edges are satisfied. The core challenge involves verifying whether a given configuration is valid according to the rules, which is essential for puzzle validation and solving algorithms. This paper discusses the design and implementation of a Java class, Skyscraper, that fulfills this purpose by providing robust verification and display functionalities.

At the heart of the Skyscraper class are private variables that represent the current configuration of the board, including the grid of skyscraper heights. The class must implement the method verifyPlacement(), which ensures that each row and column contains unique skyscraper heights, thereby satisfying the fundamental placement rules of the puzzle. This validation is crucial as it prevents conflicts and ensures the integrity of the puzzle state before further evaluation or display.

The loadPuzzle() method facilitates reading puzzle configurations from standard input, adhering to specified input standards. It reads the grid dimension followed by the grid layout, updating the class variables accordingly. This flexibility allows users to input diverse puzzles dynamically, supporting a wide range of puzzle sizes and configurations.

The print() method outputs the current state of the puzzle in a clear, formatted manner as prescribed. It provides a straightforward visual representation, assisting users in understanding the current configuration. The printWithVisibility() method enhances this by also displaying the visibility scores, which are calculated based on the number of skyscrapers visible from each side, following the rules of the game.

Calculating visibility involves evaluating each row and column from the perspective of each viewpoint (top, bottom, left, right) and counting how many skyscrapers are visible based on their heights. Private helper methods can be implemented to perform these calculations efficiently and accurately, encapsulating the logic within the class.

Design considerations emphasize encapsulation and modularity, with all helper methods declared private and class variables kept hidden to preserve integrity. The Skyscraper class is designed to be the central component, with a main method that orchestrates loading a puzzle, verifying its validity, and displaying information accordingly. This modular architecture simplifies testing and potential extensions.

In conclusion, this implementation provides a comprehensive framework for validating and visualizing skyscraper puzzles. It ensures that configurations meet core placement rules and offers clear visual feedback, aiding users and developers alike. Proper documentation and clean code structure further enhance maintainability and usability of the program.
