CodeChefOpen on judge ↗

Alice received an encoded message from her friend Bob, who used a special encoding scheme. The message consists of only digits, and each digit is mapped to a character as follows: 1 -> 'A' 2 -> 'B' 3 -> 'C' ... 26 -> 'Z' Alice wants to decode the message and find out how many different ways it can be decoded. However, she needs your help to write a program to count the possible decoding methods.
