In this exercise, you will develop a function named 'decode$($message$\_$file$)$: This function should read an encoded message from a $.$txt file and return its decoded version as a string.

Note that you can write your code using any language and IDE you want $($Python is preferred if possible, but not mandatory$).$

Your function must be able to process an input file with the following format:

$3$ love

$2$ dogs

$4$ cats

$1$ I

$5$ you

$23$

$456$

$1$: I

$6$: computers

and your function should return the string "I love computers".

Please submit the complete code for the decode function along with a brief explanation of how your code works:

Your explanation should be written as a few sentences at minimum, please don't rely just on comments.
