扁平的MutableList元素每隔若干元素一组装入新MutableList,Kotlin
fun main(args: Array<String>) {val array = arrayOf("a", "b", "c", "d", "e", "f", "g", "h", "i", "j")val STEP = 3 //3个元素一组var k = 0val lists = mutableListOf<MutableList<String>>()for (i in array.indices step STEP) {val temp = mutableListOf<String>()for (j in 0 until STEP) {k = i + jif (k >= array.size) {break}temp.add(array[k])}lists.add(temp)}lists.forEachIndexed { index, s ->println(s)}
}
[a, b, c]
[d, e, f]
[g, h, i]
[j]
