This is a really good example of a challenge that needs to be thoroughly commented. Imagine trying to work with all these different answers and figure out what is going on! Comment your code people lol

I'm not sure but I had been doing this same code and i am getting an error

Didn't exactly feel like an 8 kyu exercise. The implementation was simply enough, but the logic I feel like is a bit of a head scratcher.

Basically the line breaks serve to visually structure the final string, so there is no need for one at the end.

Approved.

What was the reason for having the last line with no line break?

Please review and approve my translation thank you for the good Kata.

Here is the first sample test which shows an expected result having no trailing space. Following that, we can see the results of running your code which shows that you returned first, and then finally what is expected of the test. Your code is definitely producing a trailing \n, and the kata tests are correct.

Test.assert_equals(multi_table(5), '1 * 5 = 5\n2 * 5 = 10\n3 * 5 = 15\n4 * 5 = 20\n5 * 5 = 25\n6 * 5 = 30\n7 * 5 = 35\n8 * 5 = 40\n9 * 5 = 45\n10 * 5 = 50')

'1 * 5 = 5\n2 * 5 = 10\n3 * 5 = 15\n4 * 5 = 20\n5 * 5 = 25\n6 * 5 = 30\n7 * 5 = 35\n8 * 5 = 40\n9 * 5 = 45\n10 * 5 = 50\n'
#should equal
'1 * 5 = 5\n2 * 5 = 10\n3 * 5 = 15\n4 * 5 = 20\n5 * 5 = 25\n6 * 5 = 30\n7 * 5 = 35\n8 * 5 = 40\n9 * 5 = 45\n10 * 5 = 50'

I am facing that same problem...

The expected result shows that the basic tests require the trailing '\n' to pass them. My code does not provide that. When I run my solution, it literally prints the exact result requested in the kata. Try it.

your function returnsundefined, it should return a string
if you look at your error messages they probably tell you this

Read this paragraph of FAQ.

With what you provided, no.

You can try providing input that fails, expected output and your output, OR provide your code.
