  智力题
  1.烧一根不均匀的绳子,从头烧到尾总共需要1个小时,问如何用烧绳子的方法来确定半小时的时间呢?
  2.10个海盗抢到了100颗宝石,每一颗都一样大小且价值连城。他们决定这么分:
  (1)抽签决定自己的号码(1~10);
  (2)首先,由1号提出分配方案,然后大家表决,当且仅当超过半数的人同意时,按照他的方案进行分配,否则将被扔进大海喂鲨鱼;
  (3)如果1号死后,再由2号提出分配方案,然后剩下的4个人进行表决,当且仅当超过半数的人同意时,按照他的方案进行分配,否则将被扔入大海喂鲨鱼;
  (4)依此类推……
  条件:每个海盗都是很聪明的人,都能很理智地做出判断,从而做出选择。
  问题:第一个海盗提出怎样的分配方案才能使自己的收益最大化?
  3.为什么下水道的盖子是圆的?
  4.中国有多少辆汽车?
  5.你让工人为你工作7天,回报是一根金条,这根金条平分成相连的7段,你必须在每天结束的时候给他们一段金条。如果只允许你两次把金条弄断,你如何给你的工人付费?
  6.有一辆火车以每小时15公里的速度离开北京直奔广州,同时另一辆火车以每小时20公里的速度从广州开往北京。如果有一只鸟,以30公里每小时的速度和两辆火车同时启动,从北京出发,碰到另一辆车后就向相反的方向返回去飞,就这样依次在两辆火车之间来回地飞,直到两辆火车相遇。请问,这只鸟共飞行了多长的距离?
  7.你有两个罐子以及50个红色弹球和50个蓝色弹球,随机选出一个罐子,随机选出一个弹球放入罐子,怎样给出红色弹球最大的选中机会?在你的计划里,得到红球的几率是多少?
  8.想像你站在镜子前,请问,为什么镜子中的影像可以左右颠倒,却不能上下颠倒呢?
  9.如果你有无穷多的水,一个3公升的提捅,一个5公升的提捅,两只提捅形状上下都不均匀,问你如何才能准确称出4公升的水?
  10.你有一桶果冻,其中有黄色、绿色、红色三种,闭上眼睛抓取同种颜色的两个。抓取多少次就可以确定你肯定有两个同一颜色的果冻?
  11.连续整数之和为1000的共有几组?
  12.从同一地点出发的相同型号的飞机,可是每架飞机装满油只能绕地球飞半周,飞机之间可以加油,加完油的飞机必须回到起点。问至少要多少架次,才能满足有一架绕地球一周。
  参考答案:
  1.两边一起烧。
  2.96,0,1,0,1,0,1,0,1,0。
  3.因为口是圆的。
  4.很多。
  5.分1,2,4。
  6.6/7北京到广州的距离。
  7.100%。
  8.平面镜成像原理(或者是“眼睛是左右长的”)。
  9.3先装满,倒在5里,再把3装满,倒进5里。把5里的水倒掉,把3里剩下的水倒进5里,再把3装满,倒进5里,ok!
  10.一次。
  11.首先1000为一个解。连续数的平均值设为x,1000必须是x的整数倍。假如连续数的个数为偶数个,x就不是整数了。x的2倍只能是5,25,125才行。因为平均值为12.5,要连续80个达不到。125/262.5是可以的。即62,63,61,64,等等。连续数的个数为奇数时,平均值为整数。1000为平均值的奇数倍。10002×2×2×5×5×5;x可以为2,4,8,40,200排除后剩下40和200是可以的。所以答案为平均值为62.5,40,200,1000的4组整数。
  12.答案是5架次。一般的解法可以分为如下两个部分:
  (1)直线飞行
  一架飞机载满油飞行距离为1,n架飞机最远能飞多远?在不是兜圈没有迎头接应的情况,这问题就是n架飞机能飞多远?存在的极值问题是不要重复飞行,比如两架飞机同时给一架飞机加油且同时飞回来即可认为是重复,或者换句话说,离出发点越远,在飞的飞机就越少,这个极值条件是显然的,因为n架飞机带的油是一定的,如重复,则浪费的油就越多。比如最后肯定是只有一架飞机全程飞行,注意“全程”这两个字,也就是不要重复的极值条件。如果是两架飞机的话,肯定是一架给另一架加满油,并使剩下的油刚好能回去,就说第二架飞机带的油耗在3倍于从出发到加油的路程上,有三架飞机第三架带的油耗在5倍于从出发到其加油的路程上,所以n架飞机最远能飞行的距离为s1+1/3+…+1/(2n+1)这个级数是发散的,所以理论上只要飞机足够多最终可以使一架飞机飞到无穷远,当然实际上不可能一架飞机在飞行1/(2n+1)时间内同时给n1个飞机加油。
  (2)可以迎头接应加油
  一架飞机载满油飞行距离为1/2,最少几架飞机能飞行距离1?也是根据不要重复飞行的极值条件,得出最远处肯定是只有一架飞机飞行,这样得出由1/2处对称两边1/4肯定是一架飞机飞行,用上面的公式即可知道一边至少需要两架飞机支持,(1/3+1/5)/2>1/4(左边除以2是一架飞机飞行距离为1/2),但是有一点点剩余,所以想像为一个滑轮(中间一个飞机是个绳子,两边两架飞机是个棒)的话,可以滑动一点距离,就说加油地点可以在一定距离内变动(很容易算出来每架飞机的加油地点和加油数量,等等)
  

  数学篇
  1.1000!有几位数,为什么?
  2.F(n) 1 n>8 n<12
  F(n) 2 n<2
  F(n) 3 n 6
  F(n)4 n other
  使用+ * /和sign(n)函数组合出F(n)函数
  sign(n) 0 n 0
  sign(n)1 n<0
  sign(n) 1 n>0
  3.编一个程序求质数的和,例如F(7) 1+3+5+7+11+13 +17 57。
  
 

 
  逻辑推理题
  1.此题源于1981年柏林的德国逻辑思考学院,98%的测验者无法解答此题。
  有五间房屋排成一列;所有房屋的外表颜色都不一样;所有的屋主来自不同的国家;所有的屋主都养不同的宠物;喝不同的饮料;抽不同的香烟。
  (1)英国人住在红色房屋里;(2)瑞典人养了一只狗;(3)丹麦人喝茶;(4)绿色的房子在白色的房子的左边;(5)绿色房屋的屋主喝咖啡;(6)吸Pall Mall香烟的屋主养鸟;(7)黄色屋主吸Dunhill香烟;(8)位于最中间的屋主喝牛奶;(9)挪威人住在第一间房屋里;(10)吸Blend香烟的人住在养猫人家的隔壁;(11)养马的屋主在吸Dunhill香烟的人家的隔壁;(12)吸Blue Master香烟的屋主喝啤酒;(13)德国人吸Prince香烟;(14)挪威人住在蓝色房子隔壁;(15)只喝开水的人住在吸Blend香烟的人的隔壁
  问:谁养鱼?
   提示:首先确定
  房子颜色:红、黄、绿、白、蓝 Color 1 2 3 4 5
  国籍:英、瑞、丹、挪、德=> Nationality 1 2 3 4 5
  饮料:茶、咖、奶、酒、水=> Drink 1 2 3 4 5
  烟:PM、DH、BM、PR、混=> Tobacco 1 2 3 4 5
  宠物:狗、鸟、马、猫、鱼=> Pet 1 2 3 4 5
  然后有:
  (9)=>N1=挪威
  (14)=>C2=蓝
  (4)=>如C3=绿,C4=白,则(8)和(5)矛盾,所以C4=绿,C5=白
  剩下红黄只能为C1,C3
  (1)=>C3=红,N3=英国,C1=黄
  (8)=>D3=牛奶
  (5)=>D4=咖啡
  (7)=>T1=DH
  (11)=>P2=马
  那么:
  挪威 ? 英国 ? ?
  黄 蓝 红 绿 白
  ? ? 牛奶 咖啡 ?
  DH ? ? ? ?
  ? 马 ? ? ?
  (12)=>啤酒只能为D2或D5,BM只能为T2或T5=>D1=矿泉水
  (3)=>茶只能为D2或D5,丹麦只能为N2或N5
  (15)=>T2=混合烟=>BM=T5,
  所以剩下啤酒=D5,茶=T2=>丹麦=D2
  然后:
  挪威 丹麦 英国 ? ?
  黄 蓝 红 绿 白
  矿泉水 茶 牛奶 咖啡 啤酒
  DH 混合烟 ? ? BM
  ? 马 ? ? ?
  (13)=>德国=N4,PR=T4
  所以,瑞典=N5,PM=T3
  (2)=>狗=P5
  (6)=>鸟=P3
  (10)=>猫=P1
  得到:
  挪威 丹麦 英国 德国 瑞典
  黄 蓝 红 绿 白
  矿泉水 茶 牛奶 咖啡 啤酒
  DH 混合烟 PM PR BM
  猫 马 鸟 ? 狗
  所以,最后剩下的鱼只能由德国人养了。

  12.U2合唱团在17分钟内得赶到演唱会场,途中必需跨过一座桥,四个人从桥的同一端出发,你得帮助他们到达另一端,天色很暗,而他们只有一只手电筒。一次同时最多可以有两人一起过桥,而过桥的时候必须持有手电筒,所以就得有人把手电筒带来带去,来回桥两端。手电筒是不能用丢的方式来传递的。四个人的步行速度各不同,若两人同行则以较慢者的速度为准。Bono需花1分钟过桥,Edge需花2分钟过桥,Adam需花5分钟过桥,Larry需花10分钟过桥。他们要如何在17分钟内过桥呢?(有个同济的学生写文章说他当时在微软面试时就是碰到了这道题,最短只能做出在19分钟内过桥,微软的人对他讲这样的结果已经是不错的了!)

  智力题
  1.每天中午从法国塞纳河畔的勒阿佛有一艘轮船驶往美国纽约,在同一时刻纽约也有一艘轮船驶往勒阿佛。已知横渡一次的时间是7天7夜,轮船匀速航行,在同一航线,轮船近距离可见。

  2.巴拿赫病故于1945年8月31日。他的出生年份恰好是他在世时某年年龄的平方,问:他是哪年出生的?
  答案:
  设他在世时某年年龄为x,则x的平方<1945,且x为自然数。其出生年份x的平方&#61485;x&#61501;x(x&#61485;1),他在世年龄1945&#61485;x(x&#61485;1)。1945的平方根&#61501;44.1,则x应为44或略小于此的数。而x&#61501;44时,x(x&#61485;1)&#61501;44×43&#61501;1892,算得其在世年龄为1945&#61485;1892&#61501;53;又x&#61501;43时,x(x&#61485;1)&#61501;43×42&#61501;1806,得其在世年龄为1945&#61485;1806&#61501;139;若x再取小,其在世年龄越大,显然不妥。故x&#61501;44,即他出生于1892年,终年53岁。

  智力题
  1.有50家人家,每家一条狗。有一天警察通知,50条狗当中有病狗,行为和正常狗不一样。每人只能通过观察别人家的狗来判断自己家的狗是否生病,而不能看自己家的狗,如果判断出自己家的狗病了,就必须当天一枪打死自己家的狗。结果,第一天没有枪声,第二天没有枪声,第三天开始一阵枪响,问:一共死了几条狗?
  2.已知两个数字为1~30之间的数字,甲知道两数之和,乙知道两数之积,甲问乙:“你知道是哪两个数吗?”乙说:“不知道”。乙问甲:“你知道是哪两个数吗?”甲说:“也不知道”。于是,乙说:“那我知道了”,随后甲也说:“那我也知道了”,这两个数是什么?
  3.一个经理有三个女儿,三个女儿的年龄加起来等于13,三个女儿的年龄乘起来等于经理自己的年龄。有一个下属已知道经理的年龄,但仍不能确定经理的三个女儿的年龄,这时经理说只有一个女儿的头发是黑的,然后这个下属就知道了经理的三个女儿的年龄。请问三个女儿的年龄分别是多少?为什么?
  答案:
  1.死了3条(第几天枪响就有几条)。
  简单分析:从有一条不正常的狗开始,显然第一天将会听到一声枪响。这里的要点是你只需站在那条不正常狗的主人的角度考虑。
  有两条的话思路继续,只考虑有两条不正常狗的人,其余人无需考虑。通过第一天他们了解了对方的信息。第二天杀死自己的狗。换句话说每个人需要一天的时间证明自己的狗是正常的。有三条的话,同样只考虑那三个人,其中每一个人需要两天的时间证明自己的狗是正常的狗。
  2.1和4,或者4和7。
  3.分别是2,2,9。
  简单分析:
  1 1 11 11 伪穷举,呵呵
  1 2 10 20
  1 3 9 27
  1 4 8 32
  1 5 7 35
  1 6 6 36 在所有的可能性中,只有这两个相同,如果经理的年龄为其他,则他下属就可以确定三个人分别为几岁了
  2 2 9 36 所以只有两种可能:1,6,6或者2,2,9。如果是1,6,6的话,那么两个同样大的6岁的孩子应该都是黑头发
  2 3 8 40 所以只有2,2,9比较合理,大的那个是黑头发,另外两个是黄毛丫头
  2 4 7 56
  2 5 6 60
  3 3 7 42
  
  3 4 6 72
  3 5 5 75
  4 4 5 80

  凹凸电子软件笔试题
  1. Select ONE of the following projects to discuss:
  a. Signal Filtering: You are given a sampled realtime waveform consisting of a sensor reading mixed with highly periodic impulses and high frequency noise.The desired output is the realtime filtered sensor signal with the impulses and noise removed, and a readout of the impulse period. The FFT may not be used.
  b. Interrupt Processing.A headware register consisting of eight independent edge triggered latches is used to record external asynchronous interrupt requests. When any of the request bits are latched, a software interrupt is generated. The software may read the latch to see which interrupt(s) occurred. Writing a one to any latch bit will clear the latch. How does that software assure that no interrupt request is ever missed?
  c. User Interface: a prototype MP3 player interface consisting of a playlist display and a few control buttons is given to you. How would you make the interface “skinnable”,with user selected graphics, options, and control button placement?
  Each project description is incomplete. What questions would you ask to completely specify the project? What development tools would you divfer to use? What algorithm /data structures/design would you use?
  2. What program(s) have you coded for you own enjoyment (not part of a school project,not for pay). What type of software project would you most enjoy working on?
  3. Have you participated in a team programming project? What is the hardest part of programming as a team, as opposed to programming alone?

  2. Programming (Mandatory)
  Linked list
  a. Implement a linked list for integers,which supports the insertafter (insert a node after a specified node) and removeafter (remove the node after a specified node) methods;
  b. Implement a method to sort the linked list to descending order.
  3. Debugging (Mandatory)
  a. For each of the following recursive methods,enter Y in the answer box if themethod terminaters (assume i=5), Otherwise enter N.

  U2合唱团在17分钟内得赶到演唱会场,途中必需跨过一座桥,四个人从桥的同一端出发,你得帮助他们到达另一端,天色很暗,而他们只有一只手电筒。一次同时最多可以有两人一起过桥,而过桥的时候必须持有手电筒,所以就得有人把手电筒带来带去,来回桥两端。手电筒是不能用丢的方式来传递的。四个人的步行速度各不同,若两人同行则以较慢者的速度为准。Bono需花1分钟过桥,Edge需花2分钟过桥,Adam需花5分钟过桥,Larry需花10分钟过桥。他们要如何在17分钟内过桥呢?(有个同济的学生写文章说他当时在微软面试时就是碰到了这道题,最短只能做出在19分钟内过桥,微软的人对他讲这样的结果已经是不错的了!)
  
  A点到B点
  1和2过去 2分钟 2
  2过来 4分钟 2+2=4
  10和5过去 14分钟 4+10=14
  1过来 15分钟 14+1=15
  1和2过去 17分钟 15+2=17
  19分钟还很不错????
