Data Structures for Coding Interviews in JavaScript

Solution: Find k Smallest Elements in an Array

Explore how to find the k smallest elements in an unsorted array by using a MinHeap data structure. Learn the step-by-step approach to initialize the heap, populate it, and retrieve the smallest elements efficiently. Understand the time and space complexity involved to write optimized JavaScript code for this common interview problem.

We'll cover the following...

Statement

Given an unsorted array arr and an integer k, find the k smallest elements from the array using a Heap.

Constraints:

  • 1≤1 \leq arr.length ≤103\leq 10^3
  • 1≤1 \leq k ≤103\leq 10^3
