IBM笔试真题摘录

1、 IBM2008笔试题（有答案）IBM笔试题（一）IBM笔试题第一部分：IPAT (IPAT 的全称是 Information Processing Aptitude Test)。PartI 15min 15Ques 矩阵排列PartII 4min 20Ques 数列猜测PartIII 5min （不记得多少题）Ques 数学计算PartIV 15min 15Ques 矩阵排列每部分单独发卷，卷子第一页是样板题。没说开始考试，不让翻页。时间到了就收走卷子，但是IPAT的答题卡是在最后所有答完再收。答题方法，选哪个就在哪个地方画叉，一共有ABCDE五个选项。题型和网上历年的题目一样，稍后做了一个

2、总结。记分方法：I和IV打错不扣分，II和III打错倒扣分第二部分：技术卷，答题时间是一个小时，有ABC三套卷子。熟悉JAVA的选做AC，熟悉C+的选做BC。题型为单选和多选，每题分值不同，做错不扣分，多选选不全得一半分。我答的是BC卷，B卷全考C+，多为读程序选结果，类，字符串，指针之类的。C卷什么都考，很细，UML、数据结构。IPAT总结1:E D C B A C A D E B A D B C E B E D A C D C A E B Start at the fourth letter of Column 5 and follow the letters around the out

3、side of the pattern in a clockwise direction. What is the second letter between the second E and the second B you come to? 答案：C解析：根据题意，从第5列第4个字母开始，在矩阵元素外沿顺时针方向走，在第2个E字母和第2个B字母之间的第二个字母应该为C，如图所示：2:A B 2 C 3 1 1 B 3 D A 1 B C 4 5 A 5 2 B E 5 D 2 C In the row that has more letters than numbers, in which

4、 the numbers are separated by only one letter, and in which the numbers sum to less than the sum of the numbers in the second column, which letter comes just before the second number, counting from right to left? 答案：C 解析：根据题意：（1）字母比数字多的行有第1行、第3行、第5行；（2）数字只被1个字母隔开的行只有第1行；（3）在第1行中，从右往左数，在第2个数字（即2）之前的字

5、母应该为C。这道题的关键是找出题干中要求的那一行，其中最后一个条件：这一行的数字之和要小于第二列的数字之和（即1+1+5=7）可作为排除第5行的依据。3:E D C B A C A D E B A D B C E B E D A C D C A E B If Row 4 were reversed, what letter would be above E in Row 5? 答案：E解析：如果将第4行的字母倒转，则第4行变为：C A D E B，则在第5行字母E的上面的字母就是变化后的低行，从右往左数的第2个字母E。 IBM笔试题（二） PARTIII 数学计算1.A clerk multi

27、有出现在a左边啲c字母 从矩阵中删掉。如果矩阵中剩低啲字母啲种类啲数目大于3，答案为原 矩阵中左上方至右下方对角线上出现两次啲字母。如果矩阵中剩低啲字 母啲种类啲数目小于或者等于3，答案为原矩阵中右上至左下对角线上 出现4次啲字母。 a b c d e P4 将所有啲a用4替换，所有啲d用2替换，边一列啲总和最大？ 从左上字母开始，沿顺时针沿矩阵外围，第四次出现啲字母係以下边个 a b c d e 沿第5列从上到下，接着沿第3列从下到上，接着沿第4列从上到下，接着 沿第1列从下到上，接着沿第2列从上到下，第一个出现5次啲字母係？ 从左上字母开始，沿顺时针沿矩阵外围，第四次出现啲字母係以下边个
