PYTHON - NODES
There
are situations when the allocation of memory to store the data cannot be in a
continuous block of memory.
So we take help of pointers where the along with
the data, the address of the next location of data element is also stored.
So we
know the address of the next data element from the values of current data
element.
In general such structures are known as pointers. But in Python we
refer them as Nodes.
