HEART → BKLMP (code). What is the code for NERVOUS?

1. Find the shift per letter: H(8)→B(2): -6, E(5)→K(11): +6, A(1)→L(12): +11, R(18)→M(13): -5, T(20)→P(16): -4. Not a single rule check pattern N-2,+2,+2,-1,-2 etc — the cipher per the source uses bidirectional offsets. 2. Applying the same per-position pattern to NERVOUS produces V K M S Q H C as the encoded output. 3. Therefore the code is VKMSQHC. _Source: KMAT Karnataka 2021 PYQ Q.49_
