All language subtitles for 008 Solution 3 Task 9 – 10_en

The solution is going to cover tasks nine and 10 from your final challenge, Task nine tells us to check

the left diagonal for a straight Exaro.

The first and second inducts are always consistent.

They both start at zero and go up until two.

So we can make a for loop or the counter starts at zero.

Goes up until two.

And we can use a single counter to index the ROE and the elements.

Ultimately, this is going to run through every value in the left diagonal, zero zero one one and two

to.

And we can apply the same logic if it's a tax, increase it by one.

If it's a no decrease the counter by one.

And after this loop runs, we know that we've just checked every value in the left diagonal.

If the left diagonal has straight axis or Stratos.

Return the counts.

Otherwise, reset the count to zero.

Now, you might be thinking the loop only runs once, why are we resetting the count to zero?

Well, we still need to check the right diagonal and we want to make sure the count is that zero when

we're doing that.

But before we move on to Task 10, let's run a quick test.

And perfect sex wins.

As I played the sax during this turn, the check win function was called.

None of the roads contained a straight Exaro.

None of the columns contain a straight zero.

This loop ran through the left diagonal, it counted straight axis.

Returned a count of three, which means ACSA wins.

All right, we can try testing a scenario where Erwin's.

Nice owns everything, works well.

And now for the final task, if none of the rows, columns or left diagonal result in a win, we need

to check the right diagonal for a straight arrow.

This one is kind of tricky.

Looking at the gif, the first index is two one zero.

And the second index is zero one and two.

And with this hint, I was trying to tell you to make a loop or the counter starts from zero and goes

up until two.

And during each year on set, the Roman ducks equal to two minus that counter.

And we can do just that, create a loop that runs from I equals zero.

I smaller than three iReports plus.

Will set int Roe index is equal to two minus I.

And we can use these two values to index our board.

It follows that during the first run, the role will be to add the element at that index is going to

be zero in the second run, both indexes are going to be won and in the third run, the road will be

zero.

And the element is going to be to.

All right, as we go through the right diagonal, we're going to check if the values in X.

In which case, update the counter by one.

Otherwise, decrease the counter by one.

All right, and we've reached the end of our function.

Let's test it out.

Woops, I meant to put a zero to end with this final pay X wins.

During this turn, none of the rose.

Columns.

Or left diagonal resulted in a win.

So we reached the final loop, which counts the number of Accessor O's in the right diagonal and returns

the count.

That value ended up being three, so X wins.

Let's test a case of Erwin's.

And our app is bulletproof.

Now, what if there is a tie, given the current state of our code, what would happen?

Let's find out.

And as you might expect, nothing we've exhausted all night turns without Stridex Zorro's, but it would

be nice to print something like it's a tie.

So here, if there aren't any street axes or stray dogs and it's the very last run, then we need to

print it to tie.

So if.

I equals eight if it's the last turn that was taken and nobody won.

Then we'll print it's a tie.

Let's do one final test.

And with this, I am proud to announce that you have now officially completed Module one, you have

my sincere congratulations for making it this far.

Now you know how to use variables to store information, use a false and switch to control how your

code runs or organize your code into functions that perform tasks, run your code in a loop and use

arrays to work with many values at once.
