Suppose the above file system is modified so that the index node does not contain a double indirect pointer. Instead, if the file size is larger than can be represented by the direct pointers and single indirect pointers, the last pointer in the indirect block will be used to point to another indirect block containing more pointers to data blocks. If that second indirect block fills up, its last pointer is used to point to another indirect block. This chain of indirect blocks can grow as long as necessary to accommodate a large file. Under this new indexing scheme, how many disk operations will the file system have to perform if a process reads data from the N^th block of a file? Use the same assumptions were used in the previous
