3,5升杯

有空想想 · 发表于 2006-1-21 23:51:07

你有一个大容器里有10升水，和可刚好盛3，5升水的杯子各一个。容器杯子均无刻度。

问题，你如何只用这三个容器，从那10升水里取水，让两个杯子里各有一升水？（不许浪费一滴水哟）

用3升杯取水，倒入5升杯；再取一杯水倒入5升杯，自剩1升，做一记号。

将5升杯倒空，3升杯倒入5升杯；

按记号自取一升

不许做记号，没给条件做记号。

I used to write a small program to solve 3 Water Jug problem. Some water jug problem needed minimum 98 steps to solve, I remember that. I could take the java program out to solve it. But here I want to challenge my mental ability here.

Here I assume you only allow to pour the water not allow to do other tricky actions, such as marking, eye measuring, or bla bla bla

I think if you pour a water from A jug to B jug, only two results will come out.www.ddhw.com

Jug A is empty and Jug B must have all the water which originates from A and B. If water A + water B <= Capacity of Jug B.
A is not empty and B must be full. if water A + water B > Capacity of B.

Not other possible results. The extended conclusion is that, if you pour the water between two jugs, one must either be empty or full afterward.

Since Capacity A = 3, Capacity B = 5, Capacity C >= 10, if you need 1 in A, 1 in B and 8 in C, it is impossible to get such result, due to my above analysis. None of water jugs is either empty or full. So it is impossible to get such combination.

10 - 0 - 0
7 - 3 - 0
7 - 0 - 3
4 - 3 - 3
4 - 1 - 5
4 - 1 - 0 （喝掉5升水，原题是酒，估计喝过5升酒后，人就晕了，做不下去了）
4 - 0 - 1
1 - 3 - 1
1 - 0 - 1 （再喝掉3升）
0 - 1 - 1

看，没浪费一滴水吧，至于以后跑厕所的事，偶就不管了。www.ddhw.com

In my analysis, I already said assume no tricky thing.

The original problem is here. I simply changed wine to water, and translated English into Chinese.

I believe the only trick, if we call it a trick, is we should understand "without wasting any wine" correctly.

Jean-Pierre has a big wine-vat with 10 liters of wine in it, and two wine-jugs which can hold exactly 3 and 5 liters of wine respectively.www.ddhw.com

Q: How can he get one liter of wine in each wine-jug without wasting any wine? (The jugs contain no measure bars or something)
A: These are the different stages of the wine-vat, the 3-litre-jug and the 5-litre-jug respectively:
1) 10 - 0 - 0
2) 7 - 3 - 0
3) 7 - 0 - 3
4) 4 - 3 - 3
5) 4 - 1 - 5
6) 4 - 1 - 0
7) 4 - 0 - 1
8) 1 - 3 - 1
9) 1 - 0 - 1
10) 0 - 1 - 1
In stages 5 and 8 Jean-Pierre drinks a sum of 8 liters of wine.

还以为自己没想到位

偶就讨厌那种答案明确，死算就出结果的题。所以捡些好玩的题与大家分享。别太认真呦。

你肯定是喝足了水，不渴。所以想不到喝水。话说回来，没点创意的题多没意思呀，是不？[;)]
