Write a Python program to combine two dictionaries by adding values for common keys.
d1 = {‘a’: 100, ‘b’: 200, ‘c’:300}
d2 = {‘a’: 300, ‘b’: 200, ‘d’:400}
Sample output: Counter({‘a’: 400, ‘b’: 400, ‘d’: 400, ‘c’: 300})
from collections import Counter
def combine_dictionaries(d1, d2):
counter_d1 = Counter(d1)
counter_d2 = Counter(d2)
combined_counter = counter_d1 + counter_d2
return combined_counter
# Example dictionaries
d1 = {'a': 100, 'b': 200, 'c': 300}
d2 = {'a': 300, 'b': 200, 'd': 400}
# Combine dictionaries
result = combine_dictionaries(d1, d2)
# Print the result
print(result)
