# Python: Delete the smallest element from the given Heap and then inserts a new item

## Python heap queue algorithm: Exercise-5 with Solution

Write a Python program that deletes the smallest element from a heap and then inserts a new item.

**Sample Solution**:

**Python Code:**

```
import heapq as hq
heap = [25, 44, 68, 21, 39, 23, 89]
hq.heapify(heap)
print("heap: ", heap)
hq.heapreplace(heap, 21)
print("heapreplace(heap, 21): ", heap)
hq.heapreplace(heap, 110)
print("heapreplace(heap, 110): ", heap)
```

Sample Output:

heap: [21, 25, 23, 44, 39, 68, 89] heapreplace(heap, 21): [21, 25, 23, 44, 39, 68, 89] heapreplace(heap, 110): [23, 25, 68, 44, 39, 110, 89]
