Totally agree, you can't use `at()` on a list!

The code will actually cause a compilation error in line 8.

I think the loop on line 8 could cause a runtime error since `l1.size()` might not work as expected with a list.

I feel like there might be a compilation error because of the way `l1.assign` is used. It seems like the parameters are in the wrong order.

I remember practicing a similar question where we had to use `assign`, but I can't recall if the order of parameters matters.

I think the code should compile fine, but I'm not sure about the output since the `assign` method seems a bit confusing.
