Jiggles got it right this time.. Well done Your turn.

[Jiggles]

ok,

this is sort of similar to yours,

a woman shoots her husband.
then she holds him under water for over 5 minutes.
finally, she hangs him.
but 5 minutes later they both go out together and enjoy a wonderful dinner together.
how can this be?

Is it a photograph of her husband that she shoots then develops?

[Jiggles]

yes your right bigboab,

here is the full answer-

The woman was a photographer. She shot a picture of her husband, developed it, and hung it up to dry.

Given a list of integer variables A. B .C. D. E. F.
each contain an integer.
You are required to reverse the contents of the variables so that A = F. B = E. C = D. D = C. E = B. F = A.
You are not allowed to use any other variables.

i.e. If you start of with

A = 1. B = 2. C = 3. D = 4. E = 5. F = 6.
You should end up with
A = 6. B = 5. C = 4. D = 3. E = 2. F = 1.

Computer programmers should find this easy.

Good one!

Obviously, normally I'd use another variable, but without that it makes it interesting.

I think this should work:

Spoiler: Show

Set A = A + F
Set F = A - F
Set A = A - F

Set B = B + E
Set E = B - E
Set B = B - E

Set C = C + D
Set D = C - D
Set C = C - D

Not very elegant, but if you work through the example..

Starting with A=1,F=6
A = A + F : ( A = 1 + 6 = 7 )
F = A - F : ( F = 7 - 6 = 1 )
A = A - F : ( A = 7 - 1 = 6 )
etc.

Thats it. Move to the top of the class.

Oh! you are at the top of the class, sorry.

Two numbers m and n are chosen such that 1 < m <= n < 100.
Mr. S. is told their sum.
Mr. P. is told their product.

The following dialogue takes place:-

Mr. P.: "I don't know the numbers."
Mr. S.: "I know that you don't know the numbers. I don't know them either."
Mr. P.: "Now I know them."
Mr. S.: "Now I know them, too."

What are the two numbers?

[bigboab]

Is this the answer?

M = 2
N = 2

[Jiggles]

here's a riddle-

If a man carried my burden, he would break his back.
I am not rich, but leave silver in my track.
What am I?
