// calculateCalories determines how many calories are burned during an activity
// Parameters:
// - activity: the type of exercise ("running", "swimming", "cycling", or any other activity)
// - duration: how long the activity was performed (in minutes)
// - intensity: a multiplier representing how intense the workout was (1.0 is normal)
// Returns:
// - the total calories burned
func calculateCalories(activity string, duration int, intensity float64) float64 {
    // TODO: Implement this function to calculate calories burned based on:
    // 1. Determine the base calorie rate per minute based on activity type:
    //    - "running" burns 10 calories per minute at intensity 1.0
    //    - "swimming" burns 8 calories per minute at intensity 1.0
    //    - "cycling" burns 7 calories per minute at intensity 1.0
    //    - Any other activity burns 5 calories per minute at intensity 1.0
    // 2. Calculate total calories as: base calories × duration × intensity
    // 3. Return the calculated calories
    
    return 0 // Replace with your implementation
}
