Dear readers, today we will be discussing a very nice problem of dp.

In this video, we discuss the Count Encodings problem where we are required to count and print all the encodings for a string as per the codes given in the question.
In this problem,
1. You are given a string str of digits. (will never start with a 0)
2. You are required to encode the str as per following rules
1 - a
2 - b
3 - c
..
25 - y
26 - z
3. You are required to calculate and print the count of encodings for the string str.
For 123 - there are 3 encodings. abc, aw, lc
For 993 - there is 1 encoding. iic
For 013 - This is an invalid input. A string starting with 0 will not be passed.
For 103 - there is 1 encoding. jc
For 303 - there are 0 encodings. But such a string maybe passed. In this case
print 0.
