You're still using <pre><code>. That can be replaced with triple backticks like so:

```
// Example code
```

Can you explain why you use a list, not an array? The suggestion was to keep array, only change the generic parameter type from string to BigInteger. A list is a mutable object. This kata does not require any mutation of the collection. So why did you go from array to list?

that last statement is now outdated

from description:

The array can contain up to 10^5 elements.

yet, the input is a List, not array.

Note: I've no idea why you use a list over an array ...

Why did you solve the issue? I will create a new one.

Thank you. Can you check it ?

yeah I guess you're right, only the description should be changed to BigInteger instead of string.

I am not sure here. If I read the task correctly, the result is a sum of digits, and it should be difficult to have a sum of digits to exceed int?

then change return type to BigInteger as well, or not?

Change from string to biginteger was per my suggestion below, which I made because I did not understand what's the point of having inputs as long strings of numbers. The strings also caused a lot of ugly code in tests.

I also don't understand why you changed from string to BigInteger. What's the purpose? And why is the return type an int, not BigInteger as well?

Description does not fit new argument type.

You must create a function ConsecutiveSum(string[] arr)

Given an unordered array of strings representing non-negative integers

@AtoG can you check it ?
