2. what's your favourite subject (I told data structures)
3. the next few questions were about data structures
4. if given a dataset would you prefer entering those numbers in an array or linked list.. why?
5. given an array of few numbers you have to find the 3rd largest number
(I gave an answer with respect to the complexities
I said I would sort the numbers in descending or ascending order and find it
so either bubble, insertion or selection
for lesser complexity merge, quick or heap)
5. So the next question was to write a code for merge sort and then the next was for quick sort
6. The next question was which language are you comfortable in (I said python or c or c++)
