This is task grader where
you will practice coding. You will have some problem
statement that you have to read with examples of what your program should display as an output and what it should do. Also, we'll have notes. As you can see, you may
submit your solution as many times as you wish and only your higher
score will be kept. On the right side, you will have a coding space where you have to put your solution and
submit the answer. Sometimes, if you have the
browser not as wide as I do, you will have to tab "Solve" where you will
have to put your code. Here you have a
statement, solve. You also have some
hints where you can request a hint here by clicking
this button if you want, it is free and it does not
interfere with your score. Let me put the window
wider again so that I have a problem statement and the coding area on the
right in the same page. I have already a solution
here that I will submit. It is evaluated and
to have more details, you have to click
this gray line here. It will open all the tests
that checked your code here, there is only one test. You can also have
some details of this test and it says your
program passed this test. Let's do a mistake here
and forget something in the answer and
submit the answer. As you can see, this
is the wrong answer. Your program displayed hello, while the expected answer
was hello MOOC to help you, the first different character is highlighted in red
as you can see. You have to check all the tests. Here, we have only one test. Don't forget to open the
testing area here and to open the specific test by clicking the gray areas here
and here again, we open the details. Also, what you can do is trying different codes by opening
different coding tabs here, and you can access the history of
everything that you have submitted or attempted
in your coding area. If you want to go to submission
that you did before, you just click on the
link and it will put in a new tab this code
that you had at that time. You can go back in history and you see all the submissions
that you have done before. That's pretty much
everything about it. Let's do the right answer
again and submit the answer. Yeah, I have a score
of 100 percent. I hope you enjoy
using this tool. If you have any questions, don't hesitate to
ask in the forums.
