What does displayvalue(1, {0,1,2}, {"Low","Medium","High"}, "Unknown") return?

• A. Low
• B. Medium
• C. High
• D. Unknown

Answer: (B)

Displayvalue translates a stored code into a user-friendly label by pairing two lists: keys and labels. It looks for the provided code in the keys list, and if found, returns the label at the same position from the labels list. Here, the code is 1, the keys are {0,1,2}, so 1 is found in the second position; the corresponding label is in {"Low","Medium","High"} at the same position, which is "Medium". Therefore, the result is Medium. If the code weren’t found, the function would return the default value "Unknown".
