Make a list of 500 three-digit numbers using a random number generator. Make a FILE with a list of the 500 numbers in order. Create artificial storage blocks on the sequential list, each of which can hold no more than 10 digits. The highest key in each storage block is recorded together with the storage block's address in an index called INDX that is opened over the sequential list FILE. Indexed Sequential search should be used to search for keys K in FILE. Compare how many comparisons the search made to how many the sequential search made using the same set of keys. Include an index over the index INDX in the extension of the implementation.
