Kotlin Program for while and do-while loop

package net.javaguides.kotlin.examples

import java.util.Arrays

fun main(args: Array < String > ) {
    val nums = arrayOf(1, 2, 3, 4, 5)
    println(Arrays.toString(nums))

    val nums2 = (3. .12).toList().toTypedArray()
    println(Arrays.toString(nums2))

    val nums3 = IntArray(5, {
        i - > i * 2 + 3
    })
    println(Arrays.toString(nums3))
}

Output:
[1, 2, 3, 4, 5]
[3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
[3, 5, 7, 9, 11]
