## Kotlin List.collate
fun <T> List<T>.collate(size: Int, step: Int = size): List<List<T>> {
    require(size >= 0) {"size must not be negative"}
    require(step <= size) {"step must be at most equal to size"}

    return collateRec(this, size, step, listOf())
}

private tailrec fun <T> collateRec(list : List<T>, size: Int, step: Int, accumulator: List<List<T>>) : List<List<T>> {
    if(list.isEmpty()) {
        return accumulator

## Kotlin Iterable.countBy extension
fun <T, M> Iterable<T>.countBy(transformer: (T) -> M) : Map<M, Int> {
    val emptyMap = mapOf<M, Int>()
    return this.fold(emptyMap) {accumulator, item ->
        val transformedItem = transformer(item)

        accumulator + Pair(transformedItem, accumulator.getOrElse(transformedItem, {0}) + 1)
    }
}
