bookChallenge: Applying String Methods in Practice

Task

Your task is the following:

  1. Create a mutable String variable named sentence with the following value: " Today we are going to lea.rn S.cala ".

  2. Remove leading and trailing whitespaces using the appropriate method and save the result in the sentence variable.

  3. Create an array of words (strings) named words based on the sentence string using the appropriate method. Words are separated by whitespaces.

  4. Iterate over the indices of the words array using the appropriate property.

  5. Remove the dots from each word by replacing the dot . with an empty string using the appropriate method.

  6. Print the current word (each word should be printed on a separate line).

object Main {
  def main(args: Array[String]): Unit = {
    ___  // Create a string
    ___  // Remove leading and trailing whitespaces
    val ___ = ___  // Create an array of words
    for (i <- ___.___) {  // Iterate over the indices
      ___  // Remove the dot
      ___  // Print the current word
    }
  }
}
