+
+When you sign up for an account somewhere, some websites do not actually store your password in their databases. 
+Instead, they will transform your password into something else using a cryptographic hashing algorithm.
+
+After the password is transformed, it is then called a password hash. 
+Whenever you try to login, the website will transform the password you tried using the same hashing algorithm and simply see if the password hashes are the same.
+
+Create the function that converts a given string into an md5 hash. The return value should be encoded in hexadecimal.
