What is the Innermost Element of a Structure?
The innermost element of a structure is the one that is closest to the root of the structure. In other words, it is the element that is farthest from any outer elements.
For example, in the following structure:
```
A
|
B
|
C
```
The innermost element is `C`, because it is the element that is farthest from any outer elements.
In general, the innermost element of a structure is the one that has no outer elements above it. It is the element that is at the "bottom" of the structure, so to speak.
