DIY: Decode Ways

Explore the Decode Ways coding challenge where you will implement a function to determine how many ways a digit-only string can be decoded into letters A-Z. This lesson helps you understand string grouping rules and apply algorithms to a common cyber security problem involving message decoding, enhancing problem-solving skills in Go.

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 ...
