is there a more kotlin way to do the following: (interate a list, selecting an item and the item before it and performing an operation on those two elements):

fun totalDistance(aList: List<Location>) : Double{
            var total: Double = 0.0
            for(x in 1..aList.size-1) {
                total += distance(aList[x], aList[x-1])
            }
            return total
        }

Maybe use https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/zip-with-next.html ?

just a FIY. there is also the more generic form of window, which is handy from time to time.
