Problem

You are tasked with creating a function that attempts to perform a division operation and handles any exceptions that may arise. The function should log the error message if an exception occurs and return a specific value based on the type of exception encountered.

Requirements:

1. Implement a function safe_divide(numerator, denominator) that takes two parameters: numerator (int) and denominator (int).
2. If the division is successful, return the result.
3. If a ZeroDivisionError occurs, log 'Cannot divide by zero' and return None.
4. If a TypeError occurs (e.g., if the inputs are not integers), log 'Invalid input type' and return None.
5. For any other exceptions, log 'An unexpected error occurred' and return None.

Examples

Example 1:

Input: safe_divide(10, 2)
Output: 5.0

Example 2:

Input: safe_divide(10, 0)
Output: None
// Log: 'Cannot divide by zero'

Example 3:

Input: safe_divide(10, 'a')
Output: None
// Log: 'Invalid input type'

Constraints

• The numerator and denominator can be any integer. If the denominator is zero, handle the exception appropriately.
