What will be the correct code for @92357?

Correct Answer

LC D W A Z

String Evaluation: Analyze the target sequence '@92357'. The first character is '@' (a symbol), and the final character is '7' (a number).Condition Check: This ......

💡 Analysis & Explanation

String Evaluation ▼

Analyze the target sequence '@92357'. The first character is '@' (a symbol), and the final character is '7' (a number).

Condition Check ▼

This structure perfectly triggers Condition (i). Consequently, the default codes for the extreme ends must be completely swapped.

Base Translation ▼

The default mapping according to the table is: @=Z, 9=C, 2=D, 3=W, 5=A, 7=L. Without conditions, it reads ZCDWAL.

Conditional Execution ▼

Applying the required swap on the first and last elements: The 'Z' at the start becomes 'L', and the 'L' at the end becomes 'Z'.

Conclusion ▼

The finalized translated output accurately forms the string LCDWAZ.
