Answer
The output will be stored as the sequence $R_{1}, R_{2}, \dots R_{m-1}$
$\bullet$ Get the letters of the alphabet $A_{1}, A_{2}, \ldots A_{26}$
$\bullet$ Get the text (including blanks and end symbol) $T_{1}, T_{2}, \ldots T_{m}$
$\bullet$ Get value for $k$
$\bullet$ Set value of $i$ to 1
$\bullet$ While $\left(T_{i}\ \neq \ "S" \right)$ do
$\bullet \quad$ If $\left(T_{i} \text { is a blank space }\right)$ then
$\bullet \quad\quad R_{i}$ is a blank space
$\bullet\quad$ Else
$\bullet \quad\quad$ Set value of $j$ to 1
$\bullet \quad\quad$ Set value of Found to NO
$\bullet \quad\quad$ While both $(j \leq 26)$ and $(\text {Found}=N O)$ do
$\bullet \quad\quad\quad$ If $T_{i}=A_{j}$ then
$\bullet \quad\quad\quad\quad$ Set Found to YES
$\bullet\quad\quad \quad\quad$ Set value of loc to $j$
$\bullet \quad\quad\quad$ Increment $j$ by 1
$\bullet\quad\quad$ End of loop
$\bullet\quad \quad$ If $l o c+k>26$ then
$\bullet\quad\quad\quad$ Set $R_{i}$ to $A_{l o c+k-26}$
$\bullet\quad\quad$ Else
$\bullet\quad\quad \quad$ Set $R_{i}$ to $A_{l o c+k}$
$\bullet\quad$ Increment $i$ by 1
$\bullet$ End of loop.
$\bullet$ Print the result: $R_{1}, R_{2}, \ldots R_{m-1}$
