How to get the current index in for each Kotlin

How to get the index in a for each loop? I want to print numbers for every second iteration

For example

    if (iteration_no %

Alternatively, you can use the withIndex library function:

for ((index, value) in array.withIndex()) {
    println("the element at $index is $value")
}
