# DIFFICULTY rating: 1 to 10, where:
# 1 is very easy
# 3 is an "easy" Exam 3 question.
# 5 is a "typical" Exam 3 question.
# 7 is a "hard" Exam 3 question.
# 10 is an EXTREMELY hard problem (too hard for a Exam 3 question)

# TIME ratings: A ROUGH estimate of the number of minutes that we
# would expect a well-prepared student to take on the problem.

# IMPORTANT: For ALL the problems in this module,
# if you reach the time estimate and are NOT close to a solution,
# STOP working on that problem and ASK YOUR INSTRUCTOR FOR HELP on it,
# in class or via Piazza.

What comes in: Nothing.
What goes out: Returns a string as described in Side effects (below).
Side effects:
Prompts the user for and inputs:
-- A positive floating point number
-- A positive integer
-- A string
in that order (via three separate INPUT statements).
Then returns the string that contains:
-- The second input, followed by a space, followed by:
-- The first input, followed by a space, followed by:
[Note the REVERSAL of the print: 2nd input THEN 1st input]
-- The sum of the first and second inputs,
followed by a space, followed by:
-- The sine of (the sum of the first and second inputs),
rounded to 2 decimal places, followed by a space, followed by:
-- The third input, repeated the second input number of times.
No input validation is required.
Examples:
Here is a sample run, where the user input is to the right of the colons:
Enter a floating point number: 1.888
Enter a positive integer: 2
Enter a string: Robots
This example returns the string
"2 1.888 3.888 -0.68 RobotsRobots"
Here is another sample run, with different inputs:
Enter a floating point number: 3.48
Enter a positive integer: 4
Enter a string: Peace & Love.
This example returns the string
"4 3.48 7.48 0.93 Peace & LovePeace & LovePeace & LovePeace & Love"
