Answer 1

def removeParenthesesWithContent(text: String): String = {
  // Remove parentheses and everything inside them
  val cleaned: String = text.replaceAll("\\([^)]*\\)", " ")

  // Collapse multiple spaces into one
  val collapsed: String = cleaned.split("\\s+").mkString(" ")

  // Final trim of leading/trailing spaces
  collapsed.trim
}

@main def run(): Unit = {
  val str: String =
    "(An) API (API) (is a) (connection) connects (between) computer programs"
