24,828 PointsAll you have to is to use a switch statement on the keys and append the correct capitals to the correct capital arrays.
for (key, value) in world {
switch key {
case "BEL", "LIE", "BGR": europeanCapitals.apped(value)
case "IND", "VNM": asianCapitals.append(value)
default: otherCapitals.append(value)
}
}
