Print all nodes less than a given value in a Min Heap
In this problem of printing all nodes in a Min Heap that have values less than a given threshold. A Min Heap is a binary tree structure where the value of each node is smaller than or equal to the values of its children. We will delve into the approach to solving this problem, present the code implementation, analyze its time complexity, and provide a brief summary.
Problem Statement and Description
Given a Min Heap and a target value k, the task is to identify and print all nodes in the Min Heap
that have values less than k. In essence, we are required to traverse the heap and output the nodes
that are smaller than the specified value k, while adhering to the Min Heap property.
Example
Consider the Min Heap depicted below:
1
/ \
2 3
/ \ / \
4 8 14 5
/ \ /\
7 6 11 9For a given target value k = 10, the nodes with values less than 10 are 7, 4, 6, 2, 8, 9, 1, 3, and
5. The expected output is 7 4 6 2 8 9 1 3 5.
Approach
The central idea for solving this problem entails traversing the Min Heap in an in-order manner while considering the values of the nodes. Since in a Min Heap, parent nodes are always smaller than their children, we can efficiently decide whether to explore a subtree or not based on the value of the current node.
Pseudocode
function printNodesLessThanK(node, k)
if node is null
return
printNodesLessThanK(node.left, k)
if node.value < k
print node.value
printNodesLessThanK(node.right, k)
end functionAlgorithm Explanation
- Create a class
Nodeto represent a node in the Min Heap, with attributesleft,right, andkey. - Develop a class
MinHeapwith attributessizeandroot. Therootattribute points to the root of the Min Heap, andsizetracks the number of nodes. - Implement the
printNodesLessThanKfunction recursively:- Base case: If the current node is null, return.
- Recursively call
printNodesLessThanKon the left subtree. - If the value of the current node is less than
k, print the value. - Recursively call
printNodesLessThanKon the right subtree.
- In the
mainfunction, instantiate aMinHeap, perform insertions to construct the Min Heap, and define the value ofk. - Call the
printNodesLessThanKfunction with the root node of the Min Heap and valuek.

The time complexity of this algorithm is O(n), where n is the number of nodes in the Min Heap. This is due to each node being visited exactly once during traversal, and the operations executed at each node taking constant time. Consequently, the time complexity scales linearly with the number of nodes in the Min Heap.
