21. Push Three Items to Heap

Write a Python program to push three items into the heap and print the items from the heap.

Sample Solution:

Python Code:

import heapq
heap = []
heapq.heappush(heap, ('V', 1))
heapq.heappush(heap, ('V', 2))
heapq.heappush(heap, ('V', 3))
for a in heap:
	print(a)

Sample Output:

('V', 1)
('V', 2)
('V', 3)
