Pseudo-code steps

1. Create a string variable (Dim ...) to hold the reversed string for output

2. Use a For / Next / Step loop to step DOWN by -1 from the LEN of the input string to 1 (the first char)

3. For each iteration, add the i-th char from the MID-dle (that is a hint) of the input string to the end of the output string in 1)

Online help is pretty good
