Python: Iterate over elements repeating each as many times as its count
1. Iterate Over Elements as Many Times as Its Count
Write a Python program that iterates over elements as many times as its count.
Note: Elements are returned in arbitrary order.
Sample Solution:
Python Code:
# Import the Counter class from the collections module
from collections import Counter
# Create a Counter object 'c' with specified initial counts for keys 'p', 'q', 'r', and 's'
c = Counter(p=4, q=2, r=0, s=-2)
# Print the elements in the Counter 'c' as a list
print(list(c.elements()))
Sample Output:
['p', 'p', 'p', 'p', 'q', 'q']
