Write a recursive function same_char_same_pos() that takes two strings as parameters. It returns the number of characters which are the same, in the same positions, in both strings. For example, same_char_same_pos("cat","bat") should return 2. For example, same_char_same_pos("cat","acat") should return 0 because, although some of the letters are the same, they are not in the same positions in the two words. Turn this in to the GradeScope assignment "Exam 2 - Same Char Same Pos." Your code should be in a file named exam2_same_char_same_pos.py.
