In a certain code, 'COMPUTER' is written as 'DPNQVUFS'. How is 'LAPTOP' written in that code?

Let's analyze the shift pattern for each letter in the word 'COMPUTER':
* $\text{C}+1=\text{D}$
* $\text{O}+1=\text{P}$
* $\text{M}+1=\text{N}$
* $\text{P}+1=\text{Q}$
* $\text{U}+1=\text{V}$
* $\text{T}+1=\text{U}$
* $\text{E}+1=\text{F}$
* $\text{R}+1=\text{S}$

Each letter is shifted by exactly $+1$ position forward. Applying this pattern to 'LAPTOP':

* $\text{L}+1=\text{M}$
* $\text{A}+1=\text{B}$
* $\text{P}+1=\text{Q}$
* $\text{T}+1=\text{U}$
* $\text{O}+1=\text{P}$
* $\text{P}+1=\text{Q}$

The resulting code is 'MBQUPQ'.
