In a code language, 'LIBERTY' is coded as ‘NKDETVA’ and 'TONIGHT' is coded as ‘VQPIIJV’. How will 'AUCTION' be coded in the same language?

Let's analyze the shift pattern of letters:
Case 1: LIBERTY → NKDETVA

L(+2)→N

I(+2)→K

B(+2)→D

E(+0)→E (Middle letter remains same)

R(+2)→T

T(+2)→V

Y(+2)→A

Let's verify this pattern with TONIGHT → VQPIIJV:

T(+2)→V

O(+2)→Q

N(+2)→P

I(+0)→I (Middle letter remains same)

G(+2)→I

H(+2)→J

T(+2)→V
The pattern is adding +2 to all positions except the middle letter (4th letter) which stays unchanged (+0).

Now apply this logic to AUCTION (7 letters):

A(+2)→C

U(+2)→W

C(+2)→E

T(+0)→T (Middle letter remains unchanged)

I(+2)→K

O(+2)→Q

N(+2)→P
