Challenge
EasycanRideRollercoaster that takes height and hasParent and returns whether a person can ride the rollercoaster.
A person can ride the rollercoaster if they meet the height requirement AND are accompanied by a parent, OR if they are tall enough to ride alone.
Conditions:
- If height is at least
140cm, they can ride alone (no parent needed) - If height is at least
120cm but less than140cm, they need a parent to ride - If height is less than
120cm, they cannot ride at all
Parameters:
height(Int): The person's height in centimetershasParent(Bool): Whether a parent is accompanying them
Returns: true if the person can ride, false otherwise (Bool)
Try it yourself
func canRideRollercoaster(height: Int, hasParent: Bool) -> Bool {
// Write code here
}
