Hello @J19APPPP0007,

Read the following two points of the question, very carefully.

  1. ‘?’ – matches any single character
    which means there must be only 1 character in place of ?

  2. ‘*’ – Matches any sequence of characters (including the empty sequence)
    which means there can be more than or equal to zero character in place of *

Your code is giving wrong outputs for testcases like:

ayghaba
a*a?a
Expected Output:
1

ayghaa
a*a?a
Expected Output:
0

aa
a?a
Expected Output:
0

aaaa
a?a
Expected Output:
0

Hope, this would help.
