The code you have does not use the first input. Instead it uses FOUR. This is the first thing to change, as you don't want to loop exactly four times, but as many times as your first input is.

Secondly, you don't need to store each next input in a separate mailbox. Instead you can immediately process the 0/1 input as it decides whether you want to add something to the result or not. So you only need to update the result depending on the input's 0/1 value. You don't need to store that 0/1 value itself -- so no need of A, B, C...etc. Instead put the IN instruction inside the loop.

Then remains what exactly you should add to the result when an input turns out to be 1. As the input is in reversed order (the least significant bits come first), you should keep track of a power of 2, which you double in each iteration of the loop. That will be the number to add to the result whenever you encounter an input of 1. Because that is how the binary system works. For instance if the input of digits is 1 1 0 1, then the calculation is:

So here is the script for that. You can run it here: first run the code snippet (which starts the LMC simulator) and then use the controls in the right panel:

1. Allocate new variables

2. Store the result to the new variables during calculation

3. Store results to the original variables from the new variables after calculation

The error message tells you that your variable (tags, filter_field, filter_country) does not exist. This means that the variables in question do not exist at the point when you try to refer to them. Things to work on to ensure this is fixed.

You should have the file containing the definition of those variables required/included. It's easy to test whether that's the case: just throw an error (not on prod, if possible) from the file that you assume to be already existent and another from the file you are trying to use it at the point where you try to use it. If the first error is thrown, then the file is evaluated at the point you try to use it. If not, then not.

Try to throw an exception from the inside of the if. If it's thrown, then export_rule is set in $_POST.

Some of your items might be missing from $_POST. It is recommended to use defaults for the case when they do not exist. Your HTML looks to have some form tags without the items that you expect. You need to have some HTML tags with their name having the value of tags, filter_field and filter_country respectively inside the form tag. If you do not have that - and that looks to be the case - then that's a problem to fix for sure.

Make sure you close your tags properly. Use an HTML validator (like this one: https://validator.w3.org/) to check what makes your HTML invalid and fix the issues.

Yes, but in NodeJS, you must explicitly export the variables/functions like this:

It's not automatic, you have to allocate more memory every time you want to resize, copy elements into new array and delete the old one. Fortunately, standard library got you covered with std::vector - an automatically resizable array.

There are several options.

1. You can catch the error from API call A before the Promise.all() and turn it into a successful request but tagged approrpiately, allowing the Promise.all() to finish.

2. You can use Promise.allSettled() to get both results, regardless of success or failure.

For the first option, you could put a .catch() handler on apiCallA() that will turn any rejection into a resolve, but will resolve with the error object which you can then later check if you need to:

Use dictionary type [String: Isbn] instead of object of type Books:

JSON syntax does not allow "raw" newlines in the middle of string values. You can use \n to include a newline (well, technically a linefeed) character. Generally, the correct thing to do is to use a proven JSON-encoding library to transform a server-side data structure into compliant JSON notation.
