In a certain code "MOUSE" is written as "PRUOC". How is "SHIFT" written in that code ?

$$\begin{gathered} \mathrm{M} \mathrm{O} \mathrm{U} \mathrm{S} \mathrm{E} \\ \downarrow +3\downarrow +3\downarrow +0\downarrow -2\downarrow -2 \\ \mathrm{Coded} \mathrm{as}: \mathrm{P} \mathrm{R} \mathrm{U} \mathrm{Q} \mathrm{C} \end{gathered}$$

Similarly,

$$\begin{gathered} \mathrm{S} \mathrm{H} \mathrm{I} \mathrm{F} \mathrm{T} \\ \downarrow +3 \downarrow +3\downarrow +0\downarrow -2\downarrow -2 \\ \mathrm{Coded} \mathrm{as}: \mathrm{V} \mathrm{K} \mathrm{I} \mathrm{D} \mathrm{R} \end{gathered}$$
