Test cases for random numbers sometimes does not include the possibility of having 9 digits in the middle of the number. If this happens, sometimes code accomplish well the task because these random tests are missing and in other cases it will fail in these cases.

Examples like 9999 -> 10000, 999 -> 1000, 99 -> 100, 9 -> 10

Programming Language: C

My algorithm outputs this for abc
Output: abc
Output: acb
Output: bac
Output: bca
Output: cba
Output: cab
But I obtained failed when the output is equal, and passed all the tests of the kata.

Hi,

this might help you

Dears,

Please let me know what is the input for each of the tests.
For the first one is clear and is displayed on the screen as
the layout and for the others? For instance, I would like to know
the input for the observed case "11".

Cheers,

That's not a mistake, that means that test expects false. Read this: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Logical_NOT

Hello

I have tried my regular expression and all passed in test.

I found a mistake that in tests before most of the validations there is a "!" character.

Please help in order to solve this kata.

Cheers,
