Cryptography, or encryption, is the process of converting plaintext $($e$.$g$.,$ a sentence or paragraph$),$ into something that should be unintelligible, called the ciphertext, The reverse process is codebreaking, or cryptanalysis, which relies on searching the encrypted message for weaknesses and deciphering it from that point. Modern security systems are heavily reliant on these processes.

In cryptography, the intended message sometimes sonsists of the first letter of every word in a string. Write a function crypt that will receive a string with the encrypted message and return the message.
