/**********************************************************************************
*
* 
* A message containing letters from A-Z is being encoded to numbers using the following mapping:
* 
* 
* 
* 'A' -> 1
* 'B' -> 2
* ...
* 'Z' -> 26
* 
* 
* 
* Given an encoded message containing digits, determine the total number of ways to decode it.
* 
* 
* 
* For example,
* Given encoded message "12",
* it could be decoded as "AB" (1 2) or "L" (12).
* 
* 
* 
* The number of ways decoding "12" is 2.
