Create a program to score a tennis match.

Requirements

1. Implement tennis scoring rules:
   • 0 points = “Love”
   • 1 point = “15”
   • 2 points = “30”
   • 3 points = “40”
   • 4+ points = “Game” (if leading by 2)
2. Handle deuce scenarios:
   • Both players at 40 = “Deuce”
   • Player ahead by 1 = “Advantage”
   • Player ahead by 2 = “Game”
3. Support match scoring:
   • Games needed to win a set (typically 6, leading by 2)
   • Sets needed to win the match (typically 2 or 3)
   • Tiebreak rules (at 6-6)

Test Cases

Scenario	Score	Expected Output
Start of Game	0-0	”Love-Love”
First Point	1-0	”15-Love”
Two Points Each	2-2	”30-30”
Deuce	3-3	”Deuce”
Advantage	4-3	”Advantage Player 1”
Game Win	4-2	”Game Player 1”
Set Win	6-4	”Set Player 1”
Match Win	6-4, 6-3	”Match Player 1”

Edge Cases to Consider

• Invalid score inputs
• Negative scores
• Impossible game states
• Tiebreak scenarios
• Match point situations

Tips

• Start with basic point scoring
• Add deuce handling next
• Then implement game scoring
• Finally add set and match scoring
• Consider using enums for score states
