Find the most frequently occurring item in the array. Example: the most frequently occurring item in [1,3,1,3,2,1] is 1. If you are given an empty array, you should return null in (Java) or None in (Python). You can assume that there is always a single, unique value that appears most frequent unless the array is empty. For instance, you won't be given an array such as [1,1,2,2]. Note: We are using list instead of arrays in Python for Simplicity. Please use predetermined function & values.

# Implement your function below.

def most_frequent(given_list): max_item = None return max_item

# NOTE: The following input values will be used for testing your solution. # most_frequent(list1) should return 1 list1 = [1, 3, 1, 3, 2, 1] # most_frequent(list2) should return 3 list2 = [3, 3, 1, 3, 2, 1] # most_frequent(list3) should return None list3 = [] # most_frequent(list4) should return 0 list4 = [0] # most_frequent(list5) should return -1 list5 = [0, -1, 10, 10, -1, 10, -1, -1, -1, 1]
