Tennis Score

Level: Intermediate

Concepts: State

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
