The function high_sess should compute the highest number of events per session of each user in the database by reading a comma-separated value input file of session data. The result should be returned from the function as a dictionary. The first column of each line in the input file is expected to contain the user’s name represented as a string. The second column is expected to contain an integer representing the events in a session. Here is an example input file:
Tony,10
            Stark,12
            Black,25
            Your program should ignore a non-conforming line like this one.
            Stark,3
            Widow,6
            Widow,14
The resulting return value for this file should be the following dictionary: { 'Stark':12, 'Black':25, 'Tony':10, 'Widow':14 }
What should replace the CODE TO FILL line to complete the function?

Solve
Consider the following Python code:
 image
In the above code, recursive_search is a function that takes a dictionary (data) and a target key (target) as arguments. It searches for the target key within the dictionary, which could potentially have nested dictionaries and lists as values, and returns the value associated with the target key. If the target key is not found, it returns None.
            
            nested_dict is a dictionary that contains multiple levels of nested dictionaries and lists. The recursive_search function is then called with nested_dict as the data and 'target_key' as the target.
            
            What will the output be after executing the above code?

A: Sum of digits of the number passed to fun.
            B: Number of digits of the number passed to fun.
            C: 0 if the number passed to fun is divisible by 10. 1 otherwise.
            D: Sum of all digits number passed to fun except for the last digit.
