You are given a string of digits that represent an encoded message. Each digit can correspond to letters (1 for A, 2 for B, …, 26 for Z). Your task is to determine the total number of different ways to decode this string into letters. For example, the string “12” can be decoded as “AB” (1, 2) or “L” (12), resulting in 2 possible decodings. The input consists of a string of digits, and you need to return the count of unique decodings that can be made from this string. Consider edge cases such as strings that begin with ‘0’ or contain invalid two-digit numbers. What is the method for calculating the number of distinct ways to decode a given numeric string?
