How to print the Fibonacci sequence in Scala

Answer 1

object FibonacciApp {
  def main(args: Array[String]): Unit = {
    
    val n = 15

    for (i <- 0 to n) {
      print(f"${fibonacci(i)}%4d")
    }
    println()
  }

  // recursively: series of 15 Fibonacci numbers (n = 15)
  def fibonacci(n: Int): Int = {
    if (n == 0) {
      0
    } else if (n == 1) {
      1
    } else {
      fibonacci(n - 2) + fibonacci(n - 1)
    }
  }
}
