easy

Complete the sentence to describe a min-heap property.

Data Structures Theory

In a min-heap, the value of each parent node is [1] than or equal to the values of its children.

Common Mistakes

Confusing min-heap with max-heap properties.

Thinking parents have greater values than children in a min-heap.

In a min-heap, each parent node's value is less than or equal to its children's values, ensuring the smallest value is at the root.

Complete the sentence to describe a max-heap property.

Data Structures Theory

In a max-heap, the value of each parent node is [1] than or equal to the values of its children.

💡 Hint

Common Mistakes

Mixing up min-heap and max-heap properties.

Assuming parents have smaller values than children in a max-heap.

In a max-heap, each parent node's value is greater than or equal to its children's values, so the largest value is at the root.

Fix the error in the statement about heap structure.

Data Structures Theory

A heap is a [1] tree where each level is completely filled except possibly the last, which is filled from left to right.

💡 Hint

Common Mistakes

Calling a heap a linear or circular tree.

Not recognizing the shape property of heaps.

A heap is a binary tree with a specific shape property: all levels are fully filled except possibly the last, which fills from left to right.

Fill both blanks to complete the min-heap property check in code.

Data Structures Theory

if node_value [1] child_value and node_value [2] sibling_value:
    # This satisfies min-heap property

💡 Hint

Common Mistakes

Using greater than operators instead of less than or equal.

Mixing operators between the two comparisons.

In a min-heap, the parent node's value must be less than or equal to both children's values to maintain the heap property.

5fill in blank

hard

Fill all three blanks to complete the max-heap property check in code.

Data Structures Theory

if parent_value [1] child1_value and parent_value [2] child2_value and is_complete_binary_tree [3] True:
    # This is a valid max-heap

Drag options to blanks, or click blank then click option'

A>=

B<=

C==

D!=

💡 Hint

Common Mistakes

Using less than or equal operators for parent-child comparison.

Using inequality operators for completeness check.

For a max-heap, the parent value must be greater than or equal to both children, and the tree must be a complete binary tree (checked by equality).
