The displayvalue() function matches a given value with an array and returns the value at the same index from a replacement array or a default value if not found. In the snippet displayvalue(1, {0, 1, 2}, {'Low', 'Medium', 'High'}, 'Unknown'), the value 1 is matched in the array {0, 1, 2} at index 1. The function then returns the value at index 1 in the array {'Low', 'Medium', 'High'}, which is 'Medium'. Reference: Appian Expression Language Documentation - Functions

It defaults to Unknown if not matched.

Medium makes sense. 1 is at index 1.

No, it’s Medium. Index 1 corresponds to 1.

I agree, it should be Low. 1 matches index 0.

I think it returns Low. The index is 0.

I didn't expect that! Thought it would be "High".

Wait, are you sure? I thought it would return "Medium".

The answer is definitely B) Medium. It's right there in the function definition - it's supposed to return the value at the same index as the matched value in the second array.

Haha, this question is a real brain-teaser! I'm going to go with B) Medium, but I'm not 100% sure. Maybe I should have paid more attention in class instead of doodling on my notebook.

This is a tricky one, but I think the correct answer is A) Low. The function is supposed to return the default value "Unknown" if the value is not found, and since the first parameter is 1, which is not in the second array, it should return "Low".

I'm pretty sure the answer is C) High. The function is supposed to return the value at the same index as the matched value, and the index of 2 in the second array corresponds to "High".

The answer is clearly B) Medium, since the second parameter in the displayvalue function is an array with the values 0, 1, 2, and the third parameter is an array with the corresponding values "Low", "Medium", "High".

It returns "Low" since 1 matches index 1.

Nope, it's definitely "Low".

I'm not sure about this one. The question says the function returns either the value at the same index or a default value if the value is not found. But the value 1 is found in the array, so I'm not sure why the default value "Unknown" would be returned. I'll have to re-read the function definition more carefully.

Okay, let me walk through this step-by-step. The function is trying to match the value 1 in the array {0, 1, 2}. Since 1 is at index 1, it should return the value at index 1 in the replacement array, which is "Medium". I'm confident that's the right answer.

Hmm, I'm a bit confused. Does the function return the value at the same index as the match, or the actual value that was matched? I need to think this through more carefully.

I think this code snippet is returning "Medium" since the value 1 matches the index 1 in the replacement array.

"High" is definitely not the answer here.

I’m confused about the index matching; I thought it would return "High" since it’s the last index.

I practiced a question like this, and I believe it returns the value at index 1, which is "Medium".

I'm not entirely sure, but I remember something similar where the index was crucial. Could it be "Medium"?

I think the function checks the first argument against the array, so it should return "Low" since 1 matches index 1.
