Stack and Queue
zhlédnutí 1KPřed 2 měsíci
Today, I will discuss two data structures: Stack and Queue.

This diagram is an overly-simplified version of the reality. I try to put these devices together in a reasonable order, only for teaching and learning purpose.

    after watching at 10 vids claiming they know how to explain it in easy to understand, they start simple then in the middle they over complicate the teaching and already confusing and abstract coz they skip in explaining the mechanism in the tagging and trunking, coz they themselves don't really understand why and what really happens on the ports, they just define this and that happens and skip the why it happened. You're the only one who really understands what you are teaching and in the most easy to understand use of words for a student
