Programming Programming

a computer can only do what it is told to do

a program is a set of instructions telling a machine what to do.

programming involves learning how to write instructions that do specific tasks

Programming is an important part of computer science ……

Puzzle 2.Puzzle 2.

You come to a fork in the road and meet a twin and ask the way to go. One twin always tells the truth One twin always tells lies.

How do you decide which way to go?

Puzzle 3.Puzzle 3. Three children sit one behind the other in a row.  The third

child can see the first two, the second child can only see the first and the first child can't see either of the other two. 

A teacher has a box of five hats, two red ones and three

black ones.  The teacher places a different hat on each of the three children. 

She instructs each one to call out the color of their hat

once they are sure of it.  All of the children are perfectly logical. 

Within a few minutes the first child correctly states the

color of her hat. 

What color is it?

Puzzle 4.Puzzle 4.

There is a certain type of rope that when lit at one end, will take an hour to burn. 

The burning however is not uniform and so it might, for example, take ten minutes for the first half to burn and fifty minutes for the second half to burn. 

You have two such ropes, but they are not identicalYour number of matches is not a concern. 

How can you measure exactly 45 minutes?

Answer puzzle 1.Answer puzzle 1.

split into 3 lots of 4 take the first 4 coins and weigh against

second lot with one weighing you know  if the heavy coin

is in the 1st or 2nd group because the balance will go down … or if they stay balanced it's in the 3rd group

now take your group of 4 coins and split into 2's now you can separate the pair and see which is the heavy coin.

To make this a more difficult problem try finding the coin of different weight without knowing if it's heavier or lighter  .... think about it...

Answer puzzle 2.Answer puzzle 2.

You say to the twin "If I asked your twin which road to take what would she say? "

....and then you take the other road...

Answer Puzzle 3Answer Puzzle 3 Black.  If the third child does not reply first then she must

be confused by the hats of the other two.  If the hats of the first two were red, then the third

would know she had a black.  The second child, hearing the silence of the third

realizes that he and the first child can't both have red hats. 

If the first child has a red hat then the second child knows, since he cannot also have a red hat, that his hat is black. 

The first child, noticing the silence of the other two, realizes that she cannot have a red hat. 

Therefore, her hat must be black.

Answer Puzzle 4.Answer Puzzle 4.

You set the two ends of one rope and one end of the second rope on fire.

Once the first rope has burned out a half hour has passed. 

By lighting the other end of the second rope at that time, it will take fifteen additional minutes for the second rope to completely burn out.
