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 or 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 wide as I do, you will have a tab, solve,
where you will have to put your code. So 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. So 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. So, 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 have
passed that we 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 Luke. To help you, the first different character
is highlighted in red as you can see. So you have to check the 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 to open the details. Also, what you can do is
trying different codes by opening different coating tabs here. And you can access the history of
everything that you have submitted or champed in your coding area. So if you want to go to
submission that you did before, you just click on the link and
until it will put in a new tab this code that
you had at that time. So you can go back in his history and you see all the submissions that
you you have done before and 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%. I hope you enjoy using this tool. If you have any questions don't
hesitate to ask in the forums.
