If a=1, b=2, c=3,....z=26. Given a string, find all possible codes that string can generate. Give a count as well as print the strings. 
 
For example: 
Input: "1123". You need to general all valid alphabet codes from this string. 
 
Output List 
aabc //a = 1, a = 1, b = 2, c = 3 
kbc // since k is 11, b = 2, c= 3
