AS EXPLAINED TO A 4 YEAR OLD CHILD, SOME QUESTIONS THAT YOU THOUGHT WERE TOUGH
Q1.How
should I explain dynamic programming to a 4-year-old?
*writes
down "1+1+1+1+1+1+1+1 =" on a sheet of paper*
"What's that equal to?"
*counting* "Eight!"
*writes down another "1+" on the left*
"What about that?"
*quickly* "Nine!"
"How'd you know it was nine so fast?"
"You just added one more"
"So you didn't need to recount because you remembered there were eight! Dynamic Programming is just a fancy way to say 'remembering stuff to save time later'"

Q2.How
should I explain recursion to a 4-year-old?
A
few years later a five-year old son would show how smoothly the idea
of recursion comes to the unspoilt mind. Walking in the middle of
town he suddenly remarked , "Daddy, not every boat has a
lifeboat, has it?" question comes , "How come?" "Well,
the lifeboat could have a smaller lifeboat, but then that would be
without one."
Q3.
How should I explain a black hole to a 4-year-old?
Take
a large piece of plastic food wrap (Saran Wrap) and hold it.
- Put a small ball in the middle so that the sheet dips.
- Pour a couple of drops of water on the sheet. They should roll down the wrap towards the ball. This illustrates gravity.
- Remove the ball and have the child use his/her finger to push down and bend the sheet. They will see that the harder they push (heavier the object) the more the plastic wrap bends.
- Have them push their finger hard enough to make a hole in the wrap. That would be an extremely heavy object.
- Pour a couple of drops of water on the sheet. They should flow down and through the hole.
- Explain that a black hole is an object so heavy that it bends space so much that anything that falls in can't ever come back (like the water that fell through the hole).
Q4.
How should one explain polymorphism to a 4 year old?
A
principal looks at a student at his door, and says "Come in!".
Then he commands the student - "Sit!", and the student sits
in the chair.
When the principal goes home, he sees his dog outside. "Come in!", and then he says "Sit!", and the dog sits on the floor.
Polymorphism is the idea of using same words on to tell different "things" to perform tasks which can be somewhat different. "Sit" to the students means sit on the chair, but "Sit" to the dog is to sit on the floor.
In programming, you might have different types of buttons that control lights, heat, alarms. In each case, it is more convenient to have one set of command like "On", "Off" rather than "Activate Alarm" "Turn on heater" . This makes it easy for the programmer, because he only needs one type of buttons - those that turn things "On" or "Off" instead of designing separate buttons for the heater, alarm, lights etc.

image, the snow as well).
The dark parts of the roof (and the tree) are the darks or shadows
The rest are the mid-tones.

Q6.How
should I explain the Kashmir issue to a 4 year old?
Once
upon a time in a far away land there lived a Great King, the wisdom
of entire world was no match to his.Once
two ladies came to his court to decide about a beautiful child they
found in a jungle. the child was so beautiful that both the
ladies want it for themselves.The king decided the child
should decide his own fate and asked to leave the child alone but the
ladies were so fascinated with this child that they decide to grab
the child by force. During the tussle they grabbed the sword and cut
the child into two pieces. They took a piece, both ladies became
happy, one become more happy because she got the face of the child
and other less as she got the limbs. By luck or the will of
God the child did not die and is still alive but the child bleeds
daily with a hope that one day both the so called moms will
understand or the King will interfere to save him from this agony and
help him to live his own life.
- King - United Nation
- Lady 1 - India
- Lady 2 - Pakistan
- Child - Kashmir
- Piece 1 - Indian occupied Kashmir
- Piece 2 - Pakistan occupied Kashmir
That was a compilation of some of the tough question that were answered by few people so beautifully that I thought were completely worth sharing. Sometime all it takes is the correct way to explain and the correct teacher .This was the perfect example.
