March 2018 - Challenge
Before Alice enters the room, she and Bob agree on a plan. Their strategy is to declare the unknown (as yet) vowel as a function of the new state of the switches.
What exactly is their suggestion?
Supply your answer as a 64-long string of vowels: the first representing when all six switches are off; the second representing when the first five are off and the last is on; ... until the last vowel representing when all six switches are on.
For example, a similar challenge with just three switches and three letters A, B, and C can be solved (why?) by AABCCBAC, which stands for:
A A B C C B A C 0 0 0 0 1 1 1 1 0 0 1 1 0 0 1 1 0 1 0 1 0 1 0 1
