DIY: Decode Ways

Explore how to decode numerical messages by mapping digits to letters using Rust. Understand multiple decoding possibilities and implement a function to count valid decoding ways, enhancing your skills in cybersecurity-related coding problems.

Problem statement

A message containing the letters from A-Z can be encoded into a string of numbers, using the following mapping:

'A' -> "1"
'B' -> "2"
...
'Z' -> "26"

To decode an encoded message, all the digits must be grouped and then mapped back into letters, using the reverse of the mapping ...
