How much memory would you need to store every possible phone?
Take the largest phone number possible: 999 999 9999 (or in your example, 999 999 999), then convert it to base 2, to figure out what the largest number of bits required is. So all numbers can be stored using 30 or 34 bits each, not 36.
Who is the best person to memorize phone numbers for?
If you have many shmoopies, memorize all of their phone numbers. Your parents and siblings. Your financial advisor, bank manager, or anyone else who can help you get to your assets remotely.
