Implement a Solution class that manages a point card.

Methods to Implement

• Solution(String ownerName): Constructor. Receives owner name and initializes points to 0
• void addPoints(int points): Adds points. If a negative value is passed, prints Error: Points cannot be negative to stdout and returns without modifying points
• boolean usePoints(int points): Deducts points. Returns true and subtracts if balance is sufficient; returns false if insufficient
• int getPoints(): Returns current point balance
• String getRank(): Returns rank string based on points (≥100 → "Gold", ≥50 → "Silver", otherwise → "Bronze")
• String getOwnerName(): Returns the owner name
