In Nico Cipher, encoding is done by creating a numeric key and assigning each letter position of the message with the provided key.

Create a function that takes two arguments, key anc and returns the encoded message.

There are some variations on the rules of encipherment. One version of the cipher rules are outlined below:Step $1$: Assign numbers to sorted letters from the key:

Step $2$: Assign numbers to the letters of the given message:

$2,3,1,5,4$

$--,-,-,-,-$

$m,u,b,a,s$

$h,i,r,h,a$

$s,s,a,n$
