Problem 3 (RSA Encryption Scheme): Alice wants to send Bob a message m that is the price she is willing to pay for his used car (m is just an integer in binary). She uses the RSA algorithm to encrypt m into the ciphertext c using Bobs public key, so only he can decrypt it. But, Eve has intercepted c and she also knows Bobs public key. Explain how Eve can alter the ciphertext C to change it into C0 so that if she sends C0 to Bob (with Eve pretending to be Alice), then, after Bob has decrypted C0, he will get a plaintext message that is twice the value of M.
