A group of numbers and symbols is coded using letter codes as per the codes given below and the conditions that follow.

Number/symbol 2 @ 9 5 $ & 3 % # 7 + 4 8 6
Code T F A J L E W Q D P R B U S

Conditions:
If the first element is a symbol and the last a number, the codes for these two (the first and the last elements) are to be interchanged.
If the first element is an odd number and the last an even number, the first and last elements are to be coded as *.
If both second and third elements are perfect squares, the third element is to be coded as the code for the second element.
If none of the above conditions are met, then the elements are to be simply coded as per the codes given in the question.

What will be the code for the following group?

💡 Analysis & Explanation

[Condition Testing Protocol] ▼

We must rigidly evaluate the sequence '@247+' against the established rule hierarchy.

[Rule 1 Check] ▼

The first element '@' is a symbol, but the last element '+' is also a symbol, not a number. Condition fails.

[Rule 2 Check] ▼

The first element is a symbol, not an odd number. Condition fails.

[Rule 3 Check] ▼

The second element is '2' and the third is '4'. While '4' is a perfect square, '2' is not. Therefore, they are not BOTH perfect squares. Condition fails.

[Default Application] ▼

Since all specific override conditions fail, we apply Condition 4, which dictates direct one-to-one translation from the lookup table.

[Translation] ▼

@ -> F; 2 -> T; 4 -> B; 7 -> P; + -> R. Linking them yields FTBPR.

Conclusion ▼

The accurate code string is FTBPR.
