Solution: Find k Smallest Elements in a List

Explore how to use a MinHeap to extract the k smallest elements from an unsorted list in Python. This lesson helps you understand the heap-based approach, implement the solution, and analyze its time and space complexities for efficient element retrieval.

We'll cover the following...

Statement

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

Constraints:

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