use case 1:
scala> val prices: Seq[Double] = Seq(9.5, 3.0, 7)
scala> val sum = prices.foldLeft(0.0)(_ + _)
2use case 2:
scala> val eduprwa: Seq[String] = Seq("Data", "Science", "Prwatech")
scala> println(s"All eduprwa = ${eduprwa.foldLeft("")((a, b) => a + " eduprwa " + b)}")
use case 3:
scala> val prices: Seq[Double] = Seq(4.0, 2.0)
scala> val diff = prices.foldLeft(5.0)(_ - _)
