Mubashir Cipher

In Mubashir Cipher, encoding is done by simply replacing paired letters from the provided key.

Create a function that takes a string containing the message to be encoded with a fixed given 2D list of letters key.

There are some variations on the rules of encipherment. One version of the cipher rules are outlined below:

key = [['m', 'c'], ['u', 'e'], ['b', 'g'], ['a', 'k'],
    ['s', 'v'], ['h', 'x'], ['i', 'z'], ['r', 'y'],
    ['p', 'w'], ['l', 'n'], ['o', 'j'], ['t', 'f'], ['q', 'd']]

message = "innokodakademija is amazing !"

mubashir_cipher(message) ➞ "uqkgzf zv kckizlb !"

Step 1: Search letter in the given key and replace it with paired letter:

e = u
d = q
a = k
b = g
.
.
.
g = b

Step 2: Keep all characters (including spaces) other than letters in their original positions:

"uqkgzf zv kckizlb !"

See the below examples for a better understanding:

Examples

mubashir_cipher("mubashir is not amazing") ➞ "cegkvxzy zv ljf kckizlb"

mubashir_cipher("%$ &%") ➞ "%$ &%"

mubashir_cipher("evgeny sh is amazing") ➞ "usbulr vx zv kckizlb"
