// EXERCISE: Simplify It
//
// Can you simplify the if statement inside the code below?
//
// When:
// isSphere == true and
// radius is equal or greater than 200
//
// It will print "It's a big sphere."
//
// Otherwise, it will print "I don't know."
//
// EXPECTED OUTPUT
// It's a big sphere.
// ---------------------------------------------------------
func main() {
// DO NOT TOUCH THIS
isSphere, radius := true, 200
var big bool
if radius >= 50 {
if radius >= 100 {
if radius >= 200 {
big = true
}
}
}
if big != true {
fmt.Println("I don't know.")
} else if !(isSphere == false) {
fmt.Println("It's a big sphere.")
} else {
fmt.Println("I don't know.")
}
}
