The Clever KingDiscrete Mathematics Level 5
The suggestion is voted on by everyone else except for the king. Each voter will vote "yes" if it increases their current salary, "no" if it decreases their current salary, and abstain (which means they don't vote) if it doesn't change their salary. If there are (strictly) more people who vote "yes" than "no", then the suggestion passes.
If the king is allowed to make as many suggestions as he wants, what is the maximum salary the king can obtain?
