php算法面试题及答案:希腊人、爱尔兰人、葡萄牙人去酒吧喝酒，猜一猜

虽然深陷债务危机，欧洲人幽默感依旧。下面这几个段子，是在新加坡《联合早报》上看到的（原文来自路透社的报道，英语原文附后）： 

脑筋急转弯 

——“为何希腊无法获得最新一轮的欧盟与国际货币基金组织援助金？”

——“因为希腊人的工作时间不够长，无法好好地填妥申请表格。”　　

——“一个希腊人、一个爱尔兰人和一个葡萄牙人相约去酒吧喝酒。你猜谁会买单？”

——“德国人”。　　

一个在斯洛伐克首都广为流传的笑话： 

“只需400欧元，你就可以拥有一个希腊人。他会住在你家，晚上很迟睡，喝你的咖啡，吃你的午餐，下午还得睡午觉，而你就得工作养活他。” 

希腊人甚至在其他国家被人嘲笑： 

一名希腊籍的路透社记者在荷兰首都阿姆斯特丹理发时，理发师问他：“你愿不愿意只剃半个头？”这是因为“剃头”（haircut）在金融术语中有扣减债券价值的意思，而欧元区最近传出希腊债券可能被迫减值50%的计划，持有希腊债券的民众当然感到不高兴。　　

不过，希腊人没有默默承受这些冷嘲热讽。一道希腊脑筋急转弯谜题就问道： 

——“灯泡坏了，需要多少个欧元区财长来更换灯泡？”

——“不需任何一个财长，因为他们会认为灯泡没问题。”　　

Heard the one about the eurozone, and the haircut?

LONDON | Wed Oct 26, 2011 3:27pm EDT

LONDON (Reuters) - Every dark cloud has its humorous lining and Europe's seemingly non-stop debt and currency crisis is no exception.

From the heavily indebted nations of the euro zone, which seem to be dragging the rest of the continent down with them, to the finance ministers, prime ministers and chancellors trying to steer the ships of state safely clear of the debt iceberg, no one escapes the humorists' barbs.

"Why did Greece fail to get the latest installment of EU/IMF aid?" goes one of the riddles making the rounds, many of which finger Greece as the most catastrophic of the euro-debt basket cases.

"Because no one in Greece works long enough to complete the application form."

"A Greek, an Irishman and a Portuguese go into a bar and order a drink. Who picks up the bill? A German."

And from the website of the German newspaper Deutsche Welle:

"There's a joke doing the rounds in Bratislava -- 'For 400 euros you can adopt a Greek. He'll stay at your place, sleep late, drink coffee, have lunch and then take a nap, so you can go to work.'"

Sometimes, it almost gets personal.

A Reuters correspondent of Greek nationality was asked, with a smirk, by a hairdresser in Amsterdam:

"So are you willing to accept a 50 percent haircut?" -- the reference being to a plan to ask Greek bondholders to take 50 percent losses -- known as a "haircut" in financial parlance.

Sometimes -- but not often -- the joke does not involve Greece.

"What's the difference between Iceland and Ireland?" went one popular riddle at the time when Ireland looked as if it would follow the tiny island nation of Iceland, whose banking system collapsed in the midst of the 2008 global financial crisis.

"One letter and about six months," was the answer.

GREEKS REACT IN KIND

The Greeks have not taken all this lying down and are especially incensed at criticism from Germany, which has revived historic enmities.

Some cartoons have sprung up depicting the "troika" of senior EU officials as soldiers in World War Two German uniform, and some Greeks are beginning to resent German tourists.

And what of the continent's heavy hitters whose meetings, mostly in Brussels but also in Luxembourg, Hungary, Finland, Poland and elsewhere have tried to come up with a rescue plan, but have dragged on for many months? Their parlays and personalities are fertile territory too.

Q: "How many European finance ministers does it take to change a light bulb?

A: None. There's nothing wrong with the light bulb."

Or:

Q: What economic model correctly forecasts the outlook for the European economy? A double-dip recession, a V-shaped recovery, or something else?

A: The bathtub. A steep decline, then a period of stagnation, then it goes down the drain.

And:

Q: How do you know it's going to be a double-dip recession?

A: Greek exports of taramosalata and tzatziki have plunged.

Germany's dominant role in the rescue talks, and German criticism of those countries that have racked up huge debts, is also a target.

The Portuguese newspaper Public's humor section, "Public Enemy," commented a few weeks ago: "Germany does not rule out leaving the euro zone, but taking all the euro notes and coins with it."

Personalities, too, are grist for the mill. The humor requires only a passing knowledge of the fact that German Chancellor Angela Merkel's country is the strongest economy in Europe, French President Nicolas Sarkozy's wife Carla Bruni just had a baby, Italian Prime Minister Silvio Berlusconi likes to party and Greek Prime Minister George Papandreou's country is the butt of almost every joke.

Hence, the official schedule for a eurozone summit this week was appended, in a wag stealth attack, as follows:

"Working session of the European Council 19.15 Working dinner 20.00 Bilateral meetings/Eurozone only session 22.00 Press Conference... 22:05 - Silvio Berlusconi heads off to the nightclub; drinks on him.......Angela declines because she wants to, Sarko because he has to, Papandreou because he can't afford the taxi back."

A little more knowledge of European history, back to the Cold War era when East was communist and had an economic union called COMECON, and West was capitalist and joined up in the EU, helps readers appreciate this update of an old Hungarian wheeze:

"What's the coat of arms of Comecon? Seven skin-and-bone cows in a green pasture milking each other. These days it's 27 cows and the EU."

Humor can also reveal the pathos behind that smiling mask, as in the Frankfurter Rundschau cartoon showing a child walking into the living room in the evening saying, "I can't sleep."

The father, looking up from the TV where he is watching a program about saving the euro, says:

"Oh, dear little bunny, were you dreaming about who might have to pay for all of this one day?"
