Coding Pattern Analysis: WET to VXDFSU

The coding pattern transforms each letter of the original word into two letters: the letter immediately preceding it and the letter immediately succeeding it.

• For the letter 'W', the code is 'V' (W minus 1) and 'X' (W plus 1).
• For the letter 'E', the code is 'D' (E minus 1) and 'F' (E plus 1).
• For the letter 'T', the code is 'S' (T minus 1) and 'U' (T plus 1).

Applying this pattern: 'WET' becomes 'VXDFSU'. The rule is: Letter $\rightarrow$ (Letter-1)(Letter+1).

Decoding MOHJAC Logic

To find the original word for the code 'MOHJAC', we reverse this pattern. The coded string 'MOHJAC' consists of pairs of letters, where each pair corresponds to one original letter.

Grouping the code into pairs:

• Pair 1: MO
• Pair 2: HJ
• Pair 3: AC

Each pair represents (OriginalLetter-1)(OriginalLetter+1).

Identifying the Original Word

We identify the middle letter for each pair, which represents the original letter:

• For 'MO': The letter that comes before 'M' and after 'O' is 'N'. (Check: $N-1 = M$, $N+1 = O$). The first original letter is 'N'.
• For 'HJ': The letter that comes before 'H' and after 'J' is 'I'. (Check: $I-1 = H$, $I+1 = J$). The second original letter is 'I'.
• For 'AC': The letter that comes before 'A' and after 'C' is 'B'. (Check: $B-1 = A$, $B+1 = C$). The third original letter is 'B'.

Combining these letters, the original word is 'NIB'.
