Suppose that the eavesdropper uses the above algorithm and has a computer that can carry out in 1 microsecond (1 millionth of a second) a division between two integers of up to 100 bits each. give an estimate of the time that it will take in the worst case to decipher the secret message if r has 100 bits.
