Q3. A tracks file with trackside as the hash key includes the records with the following trackld: 137, 135, 153, 161, 169, 177, 185, 193, 257, 136, 144, 160, 192, 256, 130, 139 and 133. Each bucket is one disk block and holds 4 records. Load these records into the file in the given order, using the hash function h(K)-K mod 8. Calculate the average number of block accesses for a random retrieval on trackld
