Write a Python program to get the frequency of the elements in a given list of lists. Use collections module

from collections import Counter
from itertools import chain
nums = [
        [1,2,3,2],
        [4,5,6,2],
        [7,1,9,5],
       ]
    
print("Original list of lists:")
print(nums)
print("\nFrequency of the elements in the said list of lists:")
result = Counter(chain.from_iterable(nums))
print(result)
