You are missing something, but we cannot tell you what you are missing without seeing your code.

closing, as this would be a suggestion anyways, not an issue. there are ways to properly free all of the memory in a standard-compliant way, and without using global variables.

assertion messages for the PHP random tests are completely unhelpful: Failed asserting that false is true

your solution is wrong, for example for observed = "00001", it will return an array like array(48) { "88818", "08818", "80818", "00818", ... } --> the 1 is treated as if it was in the 4th position, while it is in the 5th position in the input. though it is true that assertion messages are horrendous in PHP, i will raise an issue about that.

the error comes from your code: wrong index calculation, so you access invalid memory

char *pos = (char*)(pins + (sizeof(char *) * num_pins) + ((cur_idx) * len));

should be:

char *pos = (char*)pins + sizeof(char *) * num_pins + cur_idx * (len + 1);

(you forgot the + 1 for the nul terminator, and you got the pointer arithmetic wrong: ptr + n will add n * sizeof *ptr to ptr, so you were going out-of-bounds of pins. The cast to char * needs to happen right away, in order to have byte-level memory access.)

Really sorry, I didn't know that I had tried to attempt this kata a long period back.
That code was mine actually :/
My bad!

Thanks for the reply!

The initial solution in python does not have any function body for __init__, I'm not sure where you're getting that from.

That said, you should never raise a BaseException. The exact exception type doesn't matter for this kata, but it should be a concrete type, not the base class. Try raise ValueError(...), it will fix your issue.

Hi!
The author has given the following code in the object constructor in the Python Solution's preloaded code:

try:
  # parse the string
except Exception:
  raise BaseException("Error occured while parsing version!")

Now my solution works for all the fixed tests, however Test 7 Exception Calls is just not passing :c
I'm handling the rollback error as well
But it's stopping at the error I've just written above in the code.

What could be the issue?

P.S. I'm getting this error:

Traceback (most recent call last):
  File "/workspace/default/solution.py", line 14, in __init__
    self.maj = int(v[0])
               ^^^^^^^^^
ValueError: invalid literal for int() with base 10: 'a'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/workspace/default/tests.py", line 4, in <module>
    @test.describe("Sample tests")
     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    @test.it("Exception calls")

    VersionManager("a.b.c")
  File "/workspace/default/solution.py", line 20, in __init__
    raise BaseException("Error occured while parsing version!")
BaseException: Error occured while parsing version!

I'd appreciate your help!

It was nice practicing my recursion skills after long C:
Nice kata!

Nice kata! I'm getting started with recursions and this kata was a good experience practicing that + the concept of generators in Python :)

Gotta say calculating the transmission rate was the toughest part of the problem for me!
Nice kata!!

Thanks for sparing your time for letting know your thoughts!
I shall be definitely focusing on all the points you had mentioned from the next turn!
Thanks again!
