    • range

      public static IntegerSequence.Range range​(int start, int end)
      Creates a sequence [start .. end]. It calls range(start, end, 1).
      Parameters:
      start - First value of the range.
      end - Last value of the range.
      Returns:
      a range.

    • range

      public static IntegerSequence.Range range​(int start, int max, int step)

      Parameters:
      start - First value of the range.
      max - Last value of the range that satisfies the above construction rule.
      step - Increment.
      Returns:
