Euler has been summoned
in the Land of France to help some warriors that have
been captured by evil forces or hell. When he reaches the border, the Zugarramurdi’s
Witches who guard the bridge between these two lands, tell him that his only
chance to cross the bridge is by introducing the right one-digit number in the
number pad.
Euler asks for a
clue since the witches only grant him one try. The Mother Superior of the
Witches decides to help him somehow and she says… The number you
have to introduce in the number pad is the last digit of the number
Euler has checked
wit the calculator but this number has so many figures that it cannot be displayed in his calculator's screen. The Mother
Superior tells him one last clue… “Write the first 10 powers of
three and check the last digit of those numbers… can you use that information to get the digit
requested?” Deadline: October the 4th Printable Version available. PS: Jorge, Tania, Ivan, Miguel, Maria G and Veronica have won last challenge's positive! Let's start the weekend with some rythm!
