Day 2: Counting Santa's Letters

To help keep things efficient at the North Pole, Santa uses a text intercom system to pass messages. But right now that system is bugging out! It isn’t correctly decoding messages!

Problem: Create a decoder for the following encoding scheme:

• Alphabetical characters are encoded as a 2 digit number with a prepended ”\”
• a - z are encoded as 00 - 25
• A - Z are encoded as 26 - 51
• A ”\” is escaped with ”\\”
• Any other characters are left as is (the system Santa uses was made by elves, they hate latin characters so they encoded them)

There are two files: small_message_encoded.txt, which you can test on, and large_message_encoded.txt, which you should also decode and then share if you can hear “it” to prove you completed the challenge.

Example:
Input:

\33\04\11\11\14, \48\14\17\11\03!

Output:

Hello, World!
