Zadatak iz filma koji Nejtan rešava, imate i video na tu temu

Evo teksta zadatka na engleskom, (u engleskom titlu stoji ovako)
So... 20 random cards
are placed in a row all face-down.
A move consists of turning
a face-down card face-up
(koje karte, proizvoljne?)
and turning over the card
immediately to the right.
(Nije mi baš jasno gde je stavlja; može li neko da ovo objasni, eventualno skicira?)
Show that no matter
what the choice of cards to turn
this sequence of moves must
terminate. (
U kom smislu?)
i uopšte mi nije jasan zadatak, ako nastavi da preokreće poklopljene karte, posle 20 poteza su sve preokrenute. Baš mi nije jasno.
A ni ovaj sa "olimpijade"
"4n squared trains
are arranged in a 2n x 2n square"
"and each is painted with
one of four colours."
"Every 2 x 2 square of trains
involves each of the four colours."
"Every 2 x 2 square of trains..."
"Every 2 x 2 square of trains
involves each of the four colours."
"Prove that the trains..."
"Prove that the trains on
the comers of the 2n x 2n square"
"are painted with different colours."
Molio bih da ovo iskomentariše neko dobar sa matematikom i engleskim, ništa nisam uspeo da izguglam.
