1 import sys 2 for line in sys.stdin: 3 print(line, enda") Decode Numbers Programming challenge description: You are given an encoded message containing only numbers. You are also provided with the following mapping: A: 1 B: 2 Z: 26 Given an encoded message, count the number of ways it can be decoded. Input: Your program should read lines from standard Input. Each line contains an encoded message of numbers. You may assume that the test cases contain only numbers. Output: Print out the different number of ways it can be decoded. Note: 12 could be decoded as AB(1 2) or L(12). Hence the number of ways to decode 12 is 2. >_ Test Case Output Test 1 Print out the different number of ways it can be decoded.
