Quadratic sorts behavior
Is below problem meaningful? I am not able to get any logic behind it. Either am missing something or the problem is real crap. Suppose one is applying a particular quadratic sorting algorithm to an array of integers. After four iterations the array ... ? Selection sort that selects the largest element in each iteration Insertion sort i or ii ii only ii only None of these

quick sort partition procedure
Is below question and its answer correct? Or its just kind of rubbish? After one pass through the partition procedure of quick sort array stand as below: 2,1,4,5,9,7,8,10 How many possible pivots can you find in the array? (A) 1 (B) 2 (C) 3 (D) ... is once run, one element is at its final position. So if that it is the question shouldn't be the answer (A)? Am I wrong?

An operating system handles requests to resources as follows. A process (which asks for some resources, uses them for some time and then exits the system) is assigned a unique timestamp are when it starts. The timestamps are monotonically increasing with time. Let us denote the timestamp ... yes, show how. If not prove it. Can a process P ever starve? If yes, show how. If not prove it.
