You must identify the continent of the capitals on the dictionary named world, you will use the key of the dictionary to identify and assign the value to it's continent array.

for (key, value) in world {
    // Enter your code below
    switch key {
      case "BEL", "LIE", "BGR": europeanCapitals.append(value)
      case "IND", "VNM": asianCapitals.append(value)
      default: otherCapitals.append(value)
    }
    // End code
}
