Question: 
Write a function to delete the smallest element from the given heap and then insert a new item.


Model's Code:
def heap_replace(heap, item):
    import heapq
    # Remove the smallest element
    heapq.heapreplace(heap, item)
    # Return the modified heap
    return heap



Sample Correct Code:
import heapq as hq
def heap_replace(heap,a):
  hq.heapify(heap)
  hq.heapreplace(heap, a)
  return heap


Asserts:
assert heap_replace( [25, 44, 68, 21, 39, 23, 89],21)==[21, 25, 23, 44, 39, 68, 89]
assert heap_replace([25, 44, 68, 21, 39, 23, 89],110)== [23, 25, 68, 44, 39, 110, 89]
assert heap_replace([25, 44, 68, 21, 39, 23, 89],500)==[23, 25, 68, 44, 39, 500, 89]
