your two questions have the same answer: you added logs to encode(), but not to decode(). Your code correctly encodes "カタカナ" to "タモタワ", but then fails to decode the latter.

The “preserve the order” sentence was a leftover from a previous version of the kata and has now been removed. Thanks for pointing it out. The intended behavior is to output vertical directions (NORTH/SOUTH) before horizontal ones (EAST/WEST) to make this kata slightly easier.

What language? I don't see this happen in Python or Rust.

• removed using namespace std; from the initial code
• added #include <string> to the test suite

I added two examples of large values to the sample and fixed tests in all the translations.

Will do when I get a chance, probably Tuesday.

The condition "c to be less than int max" is really redundant, since all variables are ints.

I did add the following text to the description, which hopefully will clarify things:

Note: Although a, b, c are all integers, it's possible that their squares can exceed the integer bound in a statically-typed language. Such solutions should be included.

Hi eurydice5717,

I believe I have fixed the issue. Please try again and let me know.

can't verify due to not having solved in c++/not seeing your code
but - this looks to me like you're mixing up different test cases, ie. you're showing the input of one test and the expected output of a different one. be careful with how you print and how you read the output.

duplicate of this suggestion

Does that edge case (n=1, k=10) still exist? Right now, the description says (0 ≤ k ≤ n^2).
