### (Algorithmic Problem) How to find element with offset in nested lists?

To find an element with a given offset in nested lists, you can use recursion to traverse the lists and keep track of the current offset. Here is a Python implementation:

```python```def find_element(nested_list, offset):
for element in nested_list:
if isinstance(element, list):
# If the current element is a list, recursively search it
result = find_element(element, offset)
if result is not None:
return result
elif offset == 0:
# If the current element is not a list and the offset is 0, we found our element
return element
else:
# If the current element is not a list but the offset is not 0, decrement the offset
offset -= 1
return None  # If we reach the end of the list without finding the element, return None
``````

The `find_element` function takes two arguments: a nested list and an offset. It starts by iterating over the elements in the list. If the current element is a list, it recursively calls `find_element` with the same offset on that list. If the result is not `None`, it returns it immediately. Otherwise, it continues iterating over the rest of the elements.

If the current element is not a list and the offset is 0, it means we found the element we were looking for and we return it. Otherwise, if the current element is not a list but the offset is not 0, we decrement the offset and continue iterating.

If we reach the end of the list without finding the element, we return `None`.
