Many websites ask for phone numbers. the problem is that there are many different ways to represent a phone number. examples include 817-555-1234, 817 555 1234 (c), and (817) 555-1234 x23. write a raptor program which inputs a string containing a phone number in any format and outputs it in the standard format. for this assignment, the standard format is (817) 555-1234.

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?
