LATIHANThis is known as the "Die Hard Problem" because it appears in the
film Die Hard with a Vengeance. But in fact, this and other similarproblems are very old and have been the subject of much study,
particularly by computer scientists who have developed various strategies
for solving all water-jug problems. In the film, the characters played by
Bruce Willis and Samuel L. Jackson must disarm a bomb by placing
exactly four gallons of water on a scale. They have water since they are at
a fountain, but they have only two jugs, one of which holds five gallonsand the other three gallons. Can you solve the problem, and how quickly
can you do it?

Three sailors were marooned on a deserted island that was
also inhabited by a band of monkeys. The sailors worked all
day to collect coconuts but were too tired that night to count
them, They agreed to divide them equally the next morning.
During the night, one sailor woke up and decided to get hisshare. He found that he could make three equal piles, with
one coconut left over, which he threw to the monkeys.
Thereupon, he had his own share and left the remainder in
a single pile,
Later that night, the second sailor awoke and, likewise,
decided to get his share of coconuts. He also was able tomake three equal piles, with one coconut left over, which he
threw to the monkeys.
Somewhat later, the third sailor awoke and did exactly the
same thing with the remaining coconuts.
In the morning, all three sailors noticed that the pile was
considerably smaller, but each thought that he knew why
and said nothing. When they then divided the remaining
coconuts equally, each sailor received seven and one was
left over, which they threw to the monkeys.
How many coconuts were in the original pile?
