If OKLAHOMA is coded as PLMBJQOC, what will be BLANCHAR coded as?

Concept: In letter-shift coding-decoding, every letter of a word is replaced by a letter a fixed number of positions ahead in the alphabet. Different segments of the same word can carry different shift amounts, and comparing a word with its given code, letter by letter, reveals exactly what those shifts are.

Application:

1. Compare OKLAHOMA with its code PLMBJQOC by alphabet position, letter by letter.

2. The first four letters, O, K, L, A, each shift forward by 1 position to become P, L, M, B.

3. The last four letters, H, O, M, A, each shift forward by 2 positions to become J, Q, O, C.

4. Apply the same rule to BLANCHAR: split it into its first four letters, B, L, A, N, and its last four letters, C, H, A, R.

5. Shift B, L, A, N forward by 1 position each to get C, M, B, O.

6. Shift C, H, A, R forward by 2 positions each to get E, J, C, T.

7. Combining both halves gives the coded word CMBOEJCT.

Cross-check: Reversing the process on CMBOEJCT — shifting its first four letters back by 1 position and its last four letters back by 2 positions — returns exactly B, L, A, N, C, H, A, R, confirming the shift rule holds consistently in both directions.
