Remove From the End
In linked-list style questions, you often need to remove an element by counting from the end instead of the beginning. Here, the linked list is represented as a regular list of values lst, and n tells which element from the end to remove. Remove that element and return the resulting list of values; n is guaranteed to be valid.
