8 Kyu . In any case, that means you need to change your approach (at least) a bit to solve the problem. It can originate from the test suite if your solution returned a pointer that the test suite cannot reliably operate on. You can use stdout functions of your language to print function arguments (or anything you like) and it will be visible in the test output panel. When you see only one failed test and nothing after it, that might mean that its the first test which your solution failed and once you fix it, there are more to come. The function should check: The solution passes in all the tests, but when I click on "Attempt" I get these two errors: As anticipated in the comments, your solution fails the tests because the range you use in your RegExp ([A-z] = from char code 65 to char code 122) includes also some non-alphabetic characters, such as the ones used in the tests: ] (char code 93) and ^ (char code 94).

Fortunately, it does not happen often, and not every time. If the kata does not explicitly ask you to modify input arguments, make sure you do not do it. If you think that your output totally does not match the test case or its assertion message, be sure to look at the green/red message located below whatever you printed, and not above it. Theres always someone hanging out there, and usually users are very willing to help. How to reuse conditional check for each function? Sample tests provide some preliminary test cases to guide users working on their solution. To see all available qualifiers, see our documentation. The code uses the fact that in JS Number (true) == 1 and Number (false) == 0, so it's a shorter way of saying: So each x adds one to the sum, and each o subtracts one. We thought it would be useful to put a lot of the common questions we see in one place! If you really want to check that the input is title case, then you'll need to match the string from beginning to end, as mentioned in a comment (i.e., "anchor" the regex): const tests = ['This Is A Cat', 'This is a cat', 'This Is A cat']; // Is the entire string a sequence of an upper case letter, // followed by other letters and then spaces?

So check the presence of sample tests first, before you begin to rewrite your whole code ;) And keep in mind you still can use the full test suite to debug your code, using Attempt. just above. For example, C# currently has 3 versions: 7.3, 8.0, and Mono 4.3.2, and it was observed that solutions run with the Mono runtime sometimes take 2 to 3 times longer to execute (but not always). Most likely, the solution returns a valid answer and passes tests up to some point, but it's too slow and then gets forcibly aborted by the runner due to exceeded execution time. CODEWARS #2 - Check Same Case (solved in Python & Javascript) 00:00 - Intro 00:18 - Challenge 02:20 - Javascript Solution #1 13:09 - Javascript Solution #2 18:00 - Javascript Solution #3 (Refactoring with Type Casting) 20:18 - Javascript Solution #4 (Refactoring with Ternary Operator) You want to debug your solution by printing to the console, but your code printed too many steps (loop rounds or recursive calls) or got trapped in an infinite loop. Some tests are susceptible to mutation of input arguments and fail if your solution changes input objects passed to it. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. But still, it's probably some bug in your solution that causes the error. Theres usually only a couple of sample tests, they are easy, execute fast, and they do not cover too many edge cases.

Test suite attempts to perform some assertions on such invalid pointers and crashes. You must wait until you have earned at least 20 honor before you can create new collections. 36:29 - Python Solution #3 (Refactoring with Ternary Operator). And here is my code: out-of-bounds writes to arrays or memory buffers, which happen to overwrite important control structures of the program located in the neighborhood of such buffers. If sample test pass but full attempt does not, it means that solution is still not complete and has to be improved.
