1) First of all - sorry that you couldn't find the solution. The 
tour is still heavily worked on, hence I opened an issue for you

https://github.com/stonemaster/dlang-tour/issues/226

2) The example isn't that good, because neither loops nor ranges 
have been exampled before.

However that being said, here's my solution to the task. It's a 
bit more advanced as it uses `map`, but it also shows the power 
of D:

```
import std.array: array;
import std.algorithm: map;
return input.map!((x) => cast(char) (((x - 97) + shift) % 26 + 
97)).array;
```

For more info, see: 
https://dlang.org/phobos/std_algorithm_iteration.html#.map

(I opened another issue for this - 
https://github.com/stonemaster/dlang-tour/issues/227)


=> continue to rock with D and let us know all the rough corners 
that you encounter.

Thanks again!
