fun main() {
    val str = "()))(()"

    str.forEachIndexed { index, _ ->
        val str1 = str.substring(0, index)
        val str2 = str.substring(index, str.length)
        println("str1s $str1")

        println("str2 $str2")

        if (str1.count { it == '(' } == str2.count { it == ')' }) {

            return
