Assume the secret key is: (1, 2, 3, 4) -> (3, 1, 4, 2); assume the plaintext THEYLOVEIT. Remember block length should be 4 same as number of transpositions in the key, what is the cipher text?

Hint: underscores used to complete the plaintext to ensure the overall characters is divisible by the size of the transposition should be included as part of the cipher text. Also remember from the lecture slides within each block the order of positions.
