Last update on December 21 2024 07:30:36 (UTC/GMT +8 hours)

Write a Python program to implement heapsort by pushing all values onto a heap and then popping off the smallest values one at a time.

Sample Solution:

Python Code:

import heapq as hq
def heapsort(iterable):
    h = []
    for value in iterable:
        hq.heappush(h, value)
    return [hq.heappop(h) for i in range(len(h))]
print(heapsort([1, 3, 5, 7, 9, 2, 4, 6, 8, 0]))

Sample Output:

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
