Given a taxonomic table for whales with classes, orders, suborders, and families as shown below:
\begin{center}
\begin{tabular}{|c|c|}
\hline
\textbf{Class} & Mammalia \\
\hline
\textbf{Order} & Cetacea \\
\hline
\textbf{Suborder} & Mysticeti \\
\hline
\textbf{Family} & Balaenopteridae \\
\hline
\end{tabular}
\end{center}
If I have a list of whales including humpback (Megaptera novaeangliae), gray (Eschrichtius robustus), and blue (Balaenoptera musculus), how can I use Scala to classify them according to their taxonomic hierarchy using the formula:
Family > Suborder > Order > Class
Please provide sample code to achieve this classification.

Certainly! Here's a simple implementation of a taxonomic classifier in Scala:

```scala
object TaxonomicClassifier {
  def classify(taxonomy: Map[String, String], species: String): Option[String] = {
    val currentLevel = taxonomy.keys.lastOption
    if (!currentLevel.isDefined) None // reached the bottom, didn't find a match
    else if (taxonomy.contains(species)) Some(taxonomy(species))
    else classify(taxonomy.filterKeys(k => taxonomy.contains(k + " " + species)), species)
  }

  def main(args: Array[String]): Unit = {
    val taxonomy = Map(
      "Class" -> "Mammalia",
      "Order" -> "Cetacea",
      "Suborder" -> "Mysticeti",
      "Family" -> "Balaenopteridae"
    )
    val whales = List(
      "humpback" -> "Megaptera novaeangliae",
      "gray" -> "Eschrichtius robustus",
      "blue" -> "Balaenoptera musculus"
    )

    for ((whale, _) <- whales.sortByKeys) {
      println(s"Classification of ${whale}:")
      val result = classify(taxonomy, whale)
      result.foreach(println)
    }
  }
}
```

What this program does is define a `classify` function that recursively searches for a match between the species name and any of the available taxonomic levels in the `taxonomy` map. If a match is found, it returns the corresponding taxonomic level. If not, it moves up one level and keeps searching. If a match isn't found at any level, it returns `None`.

In the `main` function, we defined our sample taxonomy and a list of whales with their names as keys (in the `whales` map), sorted by their species names. The `sortByKeys` method ensures that the classification order matches our requirement of "Family > Suborder > Order > Class". Then, for each whale species, we call the `classify` function to get its classification, and print the result.

Sure, I can help you with that. In Scala, you can create case classes to represent the taxonomic hierarchy and then create instances of these classes for each whale. Here's a simple example:

```scala
// Define case classes for the taxonomic hierarchy
case class Whale(name: String, family: String, suborder: String, order: String, clazz: String)
case class Taxonomy(family: String, suborder: String, order: String, clazz: String)

// Create instances of Taxonomy for each whale
val humpbackTaxonomy = Taxonomy("Balaenopteridae", "Mysticeti", "Cetacea", "Mammalia")
val grayTaxonomy = Taxonomy("Eschrichtiidae", "Mysticeti", "Cetacea", "Mammalia")
val blueTaxonomy = Taxonomy("Balaenopteridae", "Mysticeti", "Cetacea", "Mammalia")

// Create instances of Whale using the Taxonomy instances
val humpbackWhale = Whale("humpback", humpbackTaxonomy.family, humpbackTaxonomy.suborder, humpbackTaxonomy.order, humpbackTaxonomy.clazz)
val grayWhale = Whale("gray", grayTaxonomy.family, grayTaxonomy.suborder, grayTaxonomy.order, grayTaxonomy.clazz)
val blueWhale = Whale("blue", blueTaxonomy.family, blueTaxonomy.suborder, blueTaxonomy.order, blueTaxonomy.clazz)

// Create a list of whales
val whales = List(humpbackWhale, grayWhale, blueWhale)

// Function to classify whales according to their taxonomic hierarchy
def classifyWhales(whales: List[Whale]): List[String] = {
  whales.map(whale => s"${whale.family} > ${whale.suborder} > ${whale.order} > ${whale.clazz}")
}

// Print the classified whales
classifyWhales(whales).foreach(println)
```

This code will print:

```
Balaenopteridae > Mysticeti > Cetacea > Mammalia
Eschrichtiidae > Mysticeti > Cetacea > Mammalia
Balaenopteridae > Mysticeti > Cetacea > Mammalia
```

This indicates the taxonomic hierarchy for each whale in the order: Family > Suborder > Order > Class.
