is$\_$empty$($self$)->$ bool:

This method returns True if the heap is empty; otherwise, it returns False.

The runtime complexity of this implementation must be O$(1).$

Example #$1$:

h $=$ MinHeap$([2,4,12,56,8,34,67])$

print$($h$.$is$\_$empty$())$

Output:

False

Example #$2$:

h $=$ MinHeap$()$

print$($h$.$is$\_$empty$())$

Output:
