The count for a value should start at 0, and increase by one every time the counter is passed that value. The Counter class should have the following specifications: def __init__(self) - Initializes a counter object. def add(self, ...) - Takes any number of values as arguments, and increments the count for each value accordingly. def add_list(self, values) - Takes a list of values and increments the count for each value in the list. def get(self, value) - Returns the count for the given value, or 0 if the value has no count yet. def get(self, value) - Returns a dictionary where the keys are the values passed to the Counter, and the values are the count corresponding to that value. # Example usage counter = Counter()counter.add(1, 2, 1, 3)counter.add(2, 3, 4)counter.add_list([1, 2, 3])print("Count for 5 is", counter.count(5))print("Count for 1 is", counter.count(1))print(counter.all_counts()) # Output Count for 5 is 0Count for 1 is 3{1: 3, 2: 3, 3: 3, 4: 1}
