fun minimalExample(nums: IntArray): Unit {
    for(num in nums.sliceArray(IntRange(1,nums.size-1))) println(num)
}

for (num in nums[1:])

fun minimalExampleWithDrop(nums: IntArray): Unit {
    for(num in nums.drop(1)) println(num)
minimalExampleWithDrop(intArrayOf(1,2,3,4,5,6))
// 6

    val myList = intArrayOf(1,2,3,4,5,6)
    for(i in 1 until myList.size){
        Log.d(TAG,"${myList[i]}")
    }

    val iterator = myList.iterator()
    // skip an element
    if (iterator.hasNext()) {
        iterator.next()
    iterator.forEach {
        Log.d(TAG,"it -> $it")
