JavaScript Heap Coding Practice Problems Last Updated : 25 Feb, 2025 Comments Improve Suggest changes 3 Likes Like Report Heaps are an essential data structure in JavaScript used for efficiently managing priority-based tasks. A Heap is a specialized tree-based structure that allows for quick retrieval of the smallest or largest element, making it useful for priority queues, scheduling algorithms, and graph algorithms like Dijkstra’s shortest path.This curated list of JavaScript Heap Coding Practice Problems will help you master heap operations. Whether you're a beginner or an experienced developer, these problems will enhance your understanding of heap construction, insertion, deletion, and heap-based algorithms, improving your problem-solving skills.Heap Practice ProblemsEasyHeight of HeapMinimum Cost of RopesSum of Elements Between k1'th and k2'th Smallest ElementsHuffman Decoding-1Gadgets of DoralandKth SmallestIs Binary Tree HeapKth Smallest Element in an ArrayMinimum Product of k Integers in an Array of Positive IntegersSort an Almost Sorted ArrayTop K Frequent ElementsHeight of a Complete Binary Tree (or Heap) with N NodesKth Smallest Element in a Row-wise and Column-wise Sorted 2D ArraySum of All Elements Between k1’th and k2’th Smallest ElementsMediumHeap SortCheck if a Binary Tree is a Min HeapBinary HeapHow to Implement Priority Queue – Using Heap or Array?Find Kth Smallest Element in a Row-column Sorted MatrixConnect n Ropes with Minimum CostFind K Closest NumbersSort an Almost Sorted ArrayBST to Max HeapK’th Largest Element in a StreamFind the K Numbers with Most Occurrences in the Given ArrayFind the Kth Largest Element in an ArrayMerge Overlapping IntervalsGame with StringNearly SortedRearrange CharactersMinimum Sum of Squares of Character CountsK-th Largest Sum Contiguous SubarrayHardMerge K Sorted ArraysMerge K Sorted ListsFind the Median of a Stream of Running IntegersSmallest Range in K ListsHuffman EncodingSliding Window Maximum (Maximum of All Subarrays of Size K)Merge Two Sorted Arrays in O(1) Extra Space Using Heap Create Quiz Comment S souravsharma098 Follow 3 Improve S souravsharma098 Follow 3 Improve Article Tags : JavaScript Web Technologies JavaScript-DSA JavaScript-Quiz Explore JavaScript BasicsIntroduction to JavaScript4 min readVariables and Datatypes in JavaScript6 min readJavaScript Operators5 min readControl Statements in JavaScript4 min readArray & StringJavaScript Arrays7 min readJavaScript Array Methods7 min readJavaScript Strings5 min readJavaScript String Methods9 min readFunction & ObjectFunctions in JavaScript5 min readJavaScript Function Expression3 min readFunction Overloading in JavaScript4 min readObjects in JavaScript4 min readJavaScript Object Constructors4 min readOOPObject Oriented Programming in JavaScript3 min readClasses and Objects in JavaScript4 min readWhat Are Access Modifiers In JavaScript ?5 min readJavaScript Constructor Method7 min readAsynchronous JavaScriptAsynchronous JavaScript2 min readJavaScript Callbacks4 min readJavaScript Promise4 min readEvent Loop in JavaScript4 min readAsync and Await in JavaScript2 min readException HandlingJavascript Error and Exceptional Handling6 min readJavaScript Errors Throw and Try to Catch2 min readHow to create custom errors in JavaScript ?2 min readJavaScript TypeError - Invalid Array.prototype.sort argument1 min readDOMHTML DOM (Document Object Model)8 min readHow to select DOM Elements in JavaScript ?3 min readJavaScript Custom Events4 min readJavaScript addEventListener() with Examples9 min readAdvanced TopicsClosure in JavaScript4 min readJavaScript Hoisting6 min readScope of Variables in JavaScript3 min readJavaScript Higher Order Functions7 min readDebugging in JavaScript4 min read Like
