[All ACD101 Questions]

Review the following expression rule:

union(ri!fruit, ri!vegetables)

The rule inputs are configured as text arrays.

AAll items in ri!fruit followed by items in ri!vegetables, including duplicate values.

BOnly items that are in both ri!fruit and ri!vegetables.

CAll items in ri!fruit and ri!vegetables combined, with duplicates removed.

Show Suggested Answer

Suggested Answer: B

The best practice in Appian for passing values into an interface is to use named parameters, which is demonstrated by Option B. Named parameters make the code more readable and maintainable by clearly specifying which parameter each value is being passed to. In this case, the recordId and firstName parameters are clearly being assigned the values 1 and 'Kyle' respectively. Reference:

Really? I thought it would just give unique items.

Wait, are you sure it's not B? That seems off.

I think it's C, duplicates should be removed.

I feel like I saw something about union in our notes, but I can't recall if it was about keeping duplicates or not.

I’m a bit confused; I thought union would just list everything, including duplicates, like in option A.

I remember practicing a similar question where the union removed duplicates, so I might lean towards option C.

I think the union function combines both arrays, but I'm not sure if it keeps duplicates or not.

Alright, I've got it. The rule is taking the items from ri!fruit and ri!vegetables and combining them, but it's not removing any duplicates. So the output should be all the items from both arrays, including any duplicates. That's option A.

I'm a little confused by the wording here. Is the rule actually doing a union operation, or is it just combining the two arrays in some way? I'll need to re-read this a few times to make sure I understand what it's asking for.

I think I've got this. The rule is saying "union", so I'm guessing the output will be all the items from both arrays, with any duplicates removed. That sounds like option C to me.

Okay, let's see. The rule is taking two text arrays as input, so I'm guessing the output will be some kind of combination of those two arrays. I'll need to pay close attention to the wording to figure out exactly what it's asking for.

Hmm, this is a tricky one. I'm leaning towards B, since the question mentions the rule 'union', which might have a different behavior than a regular union operation.

I'm going with C. The union operation should remove any duplicate values, so the output should be a combined list of all items from both arrays, without duplicates.

I'm not sure about this one. The question talks about a 'rule', so I'm guessing the output might be different from a standard union operation. I'll have to think about it some more.
