Sorry about that. DSAs are most certainly going to be difficult
to understand for anyone who is not familiar with the many, many
concepts involved. These concepts include data
representation, LIFO queues (stacks), state machines, arrays, and so
on. So it is only easy once you are comfortable with all these
ideas. But we gotta start somewhere and I will try my best to
avoid some of the terrible details that might hide the basic concepts.
