• These are the Placement papers which contains questions and answers asked in L&T Infotech for 2011-2012.

1.what is the order of strassens matrix multiplication?

2.you have to maintain the sorted order of integers and insert integers . which data structure would you use? (tree, list, queue, array?)

3. There are two lists of integers to be merged. Which method would you not use?

4. In an online database system when is data written to disk? (on pressing enter, when commit or update is encountered, at end of data, all of the above) (was clueless! )

5. Small prolog function which prints 2345true. You need to tell output.

6. Convert this binary into octal. 010 100 101

7. Lisp program given. what does it do? (GCD, LCM, Multiplies mxn?)

8. What is paging?

9.What should come in place of the question mark (?) in the following questions?

10. (31569 + 2488 +47936) – (227 x 96) =?

2) 60201
3) 62506
4) 60205
5) None of these

11. Cost of an item is x. It’s value increases by p% and decreases by p% Now the new value is 1 rupee, what is the actual value ?

Ans.(1000)/(1000-p*p).

12. A right circular cylinder and a cone are there. Base radius of cone is equal to radius of cylinder. What is the ratio of height to slant side if their volume are the same?

13. Distance between two poles is 50 meters. A train goes by 48 at a speed of kmph. In one minute how many poles will be crossed by the train ?
