Q: Count overlapping substrings python.

Answer: Count() function does not count the overlapping strings. For this, we need to write our own function definition.

Keep a count variable to store the count and pos to track the starting index of the sub-string. When the sub-string is encountered, increment the counter and check from the next index.

This is how we calculate the overlapping substrings.

Output: 2
