You can do this, though you are likely to run out of memory with such long strings

fun String.repeat(times: Long): String {
    val inner = (times / Integer.MAX_VALUE).toInt()
    val remainder = (times % Integer.MAX_VALUE).toInt()
    return buildString {
        repeat(inner) {
            append([email protected](Integer.MAX_VALUE))
        }
        append([email protected](remainder))
    }
}
