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.
