The partition function works in a similar way with arrays as well. Here are its different usages. Each of them works similarly, just producing lists of different types:

// Produces two listsinline fun <T> Array<out T>.partition(
    predicate: (T) -> Boolean
): Pair<List<T>, List<T>>

// Breaks original list of Byte and produces two lists of Byteinline fun ByteArray.partition(
    predicate: (Byte) -> Boolean
): Pair<List<Byte>, List<Byte>>

// Breaks original list of Short and produces two lists of Shortinline fun ShortArray.partition(
    predicate: (Short) -> Boolean
): Pair<List<Short>, List<Short>>

// Breaks original list of Int and produces two lists of Intinline fun IntArray.partition(
    predicate: (Int) -> Boolean
): Pair<List<Int
