Consider a disk pack with a seek time of $4$ milliseconds and rotational speed of $10000$ rotations per minute (RPM). It has $600$ sectors per track and each sector can store $512$ bytes of data. Consider a file stored in the disk. The file ... accessing each sector is half of the time for one complete rotation. The total time (in milliseconds) needed to read the entire file is__________________
The number of nodes of height $h$ in any $n$-element heap is ________. $h$ $2^{h}$ ceil $\left[\frac{n}{2^{h}}\right]$ ceil $\left[\frac{n}{2^{h+1}}\right]$ Answer is given as D, But I think it should be C. Because, even if you take height=1 then possible nodes are 3 and 2.
