One way to solve the exercise is as follows:
var zoo = ["🐈","🐕", "🐍", "🐕", "🐈", "🐕", "🐍", "🐕", "🐕", "🐕", "🐈", "🐍", "🐈", "🐍", "🐍", "🐈"]
var snakes: [String] = []
var cats: [String] = []
var dogs: [String] = []
for animal in zoo {
if animal == "🐈" {
cats.append(animal)
} else if animal == "🐕" {
dogs.append(animal)
} else {
snakes.append(animal)
}
}
print(snakes)
print(cats)
print(dogs)
