Kata: Counting Duplicates

Description: We need a function that takes a string and returns the count of characters (letters and digits) that appear more than once, regardless of case.

Solution Code
To solve this, we’ll use an object to track the frequency of each character. Here’s the approach:

Convert the input to lowercase to make it case-insensitive.
Use an object to count occurrences of each character.
Count characters with more than one occurrence and return that count.

Explanation:
Lowercase Conversion: The function first converts text to lowercase to handle case insensitivity.
Frequency Counting: We use an object to store the count of each character in the string.
Counting Duplicates: Finally, we iterate over the object to find characters with a count greater than one, indicating they’re duplicates.
