  • Corrections to the exercise text will be posted here
    • There is an error in the text, that says that h is the maximum x and w the maximum y. They shoud be instead  h=maximum y and w=maximum x
  • NOTICE: to disable some safety checks and the timeout, change test_01.py by setting DEBUG=True


To complete the homework:

  • Install all the required libraries (stopit included)
  • Download the HW5opt.zip file and unzip it in a directory
    • The archive contains:
      • a problem to be solved, described at the beginning of file program01.eng.py;
        • your job is to complete the ex1 function inside program01.eng.py to solve the problem – adding other functions is allowed;
      • all other libraries and test files needed to run tests on your machine.
  • Enter the HW3opt directory created by unzipping the archive and
    • rename program01.eng.py as program01.py and edit the file to solve the problem;
  • NOTICE: the program should not use input() or print(). All needed parameters are passed to the ex1 function by the test system. Your results are returned to the tests by using return.
  • BEWARE: global variables are forbidden.
  • BEWARE: it's forbidden to import other libraries apart from the ones already imported in the text.
  • NOTICE: your program should be applicable to any correct input (do not exploit data repetitions or particularities).
    • if __name__ == '__main__':
      • # Here you can enter your own test instructions
  • To test your program:
    • open an “Anaconda Prompt” window and enter the HW2req directory
    • run the following command
      • pytest test_01.py -v -rA
    • or (test printing also a list of the slowest runs)
      • pytest test_01.py -v -rA --durations 0
    • or (test printing a list of the 20 slowest functions executed)
      • pytest test_01.py -v -rA --profile
    • To stop tests at the first error, add the -x option
    • If you use Spyder:
      • you can run tests from Spyder by first installing the spyder-unittest plugin (but you cannot add parameters to the test execution);
      • you can profile the functions from Spyder by first installing the spyder-line-profiler plugin.

NOTICE: to open and edit text files in the UTF8 format, DO NOT use Notepad (as it does not handle well the Unix linefeed character '\n'). Use Spyder or Notepad++ instead.

This HW has no deadline


You are required to submit only program01.py

To do so, go to page https://q2a.di.uniroma1.it/homeworks/delivery?homework=6 and submit your file

After some minutes/hours, the homework leaderboard will be updated with your tests results, conducted in a standardized virtual machine.

You can submit your program more than once. The latest submission is the one that counts.
