something like

list.sortedBy { it.first }. fold(mutableListOf(list.size)) { result, range ->
   when {
      result.isEmpty() -> result.add(range) // first
      result.last().end < range.start -1 -> result.add(range) // no merge
      else -> result.last().let { result[result.lastIndex] = it.start .. range.end }
  }
  result
}
