+/** A: We will assume that 
+ * 1) all blue eyed people will fit on a single flight
+ * 2) all people are intelligent (or have worked out a plane beforehand).
+ * Since everybody can assume, that if the plane didn't leave after as many days as the number of blue eyed people
+ * the given person sees, she must have a blue eye also.
+ * Therefore they will leave the day after that. */
