Calculate combat damage
A simple combat system subtracts the defender's rating from the attacker's, but damage never drops below zero.
- Damage equals attack minus defense.
- A negative result is clamped to zero.
combatRound(attack: int, defense: int) → int
Go needs a compiler and Drill does not host one yet, so this page is the reference rather than an exercise: the problem, worked examples, and the solution in full. To type it out, the same problem runs in Python.
Where you start
func combatRound(attack int, defense int) int {
}Worked examples
| Call | Result |
|---|---|
combatRound(10, 5) | 5 |
combatRound(3, 7) | 0 |
combatRound(0, 0) | 0 |
combatRound(100, 100) | 0 |
Hint
Subtract, then clamp.
Reference solution in Go
func combatRound(attack int, defense int) int {
diff := attack - defense
if diff < 0 {
return 0
}
return diff
}
