arrays have a fixed size. On the other hand access to an element in the middle of the list is usually O(n), where n is the length of the list. An item in a linked list consists of a struct containing the data element and a pointer to another linked list. In C0 we have to commit to the type of element that is stored in the linked list.

Python is a strongly-typed and dynamically-typed language. Strongly-typed: Interpreter always “respects” the types of each variable.[1] Dynamically-typed: “A variable is simply a value bound to a name.” [1] Execution: Python is first interpreted into bytecode (.pyc) and then compiled by a VM implementation into machine instructions.

to the next element in its list. However, we will augment the list so that each element also has a pointer directly to head of its list. The head of the list is the representative element. We can now implement the operations as follows: MakeSet(x): just set x->head=x. This takes constant time. Find(x): just return x->head. Also takes constant time.
