These are the

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
