The following ciphertext is encrypted using a monoalphabetic substitution cipher. Use the frequency analysis technique described in the lecture to decrypt this. Show the frequency of letters in the ciphertext and show your work. You can use different tools (with citing the source) to find the frequency of letters, or write your own code. But you are not allowed to brute force the ciphertext for finding the plaintext. It is important to show your work. If you only submit the final plaintext no points will be given. Explain your thought process as you try to decrypt this. This ciphertext is included in file hw1q1cipher.txt.
