Expert Solution & Answer
Chapter 14, Problem 21E
Explanation of Solution
Given scenario:
- An attribute that stores values for names is taken, where:
- Maximum size of name can be as large as 40 characters.
- Average size is around 10 characters.
The given attribute will face two issues:
- Each name will be of different length.
- Names can be quite long as stated.
- It may result in low fan-out and a likewise increase in the height of the tree.
- Additionally, having variable length search keys will result in different nodes having different fan-outs, even if they are full.
- Prefix compression can be used to increase the fan-out of a node...

We are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7).
A code breaker manages to factories 247 = 13 x 19
Determine Alice's secret key.
To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.
Consider the following Turing Machine (TM). Does the TM halt if it begins on the empty tape? If it halts, after how many steps? Does the TM halt if it begins on a tape that contains a single letter A followed by blanks? Justify your answer.
