Method 1 : Using the json module. We can solve this particular problem by importing the json module and use a custom object hook in the json.loads() method.

Time complexity: O(n), where n is the total number of elements in the input dictionary.
Auxiliary space: O(n), where n is the total number of elements in the input dictionary

Method 2: Using the isinstance() method

We can solve this particular problem by using the isinstance() method which is used to check whether an object is an instance of a particular class or not.
