Map-1 > topping3
prev  |  next  |  chance

Given a map of food keys and topping values, modify and return the map as follows: if the key "potato" has a value, set that as the value for the key "fries". If the key "salad" has a value, set that as the value for the key "spinach".

topping3({"potato": "ketchup"}) → {"potato": "ketchup", "fries": "ketchup"}
topping3({"potato": "butter"}) → {"potato": "butter", "fries": "butter"}
topping3({"salad": "oil", "potato": "ketchup"}) → {"spinach": "oil", "salad": "oil", "potato": "ketchup", "fries": "ketchup"}

...Save, Compile, Run

public Map<String, String> topping3(Map<String, String> map) { }
