8. We have discussed three file allocation techniques for storing a file on disk,
namely contiguous allocation, linked allocation, and indexed allocation.
For each allocation method show how a file of 10 blocks would be allocated
on disk. Note that the disk is represented as 30 blocks with blocks 0, 5, 6, 15,
25 already allocated. Note you must show the entire data structure for each
allocation method as part of the answer.
