Lean-DSA

A collection of standard data structures and algorithms in lean Javascript. (Work in progress)

This is not production-grade code. The idea is to aid understanding by exposing the underlying logic in a reasonably clear way.

Binary Search Tree

  • add
  • findMin/findMax
  • find
  • isPresent
  • remove
  • getMinHeight
  • getMaxHeight
  • isBalanced
  • Depth-first search
    • inOrderTraversal
    • preOrderTraversal
    • postOrderTraversal
  • Breadth-first search
    • levelOrderTraversal

Set

  • add
  • has
  • values
  • remove
  • clear
  • size
  • union
  • intersection
  • difference
  • subset

Priority Queue

  • same as queue plus enqueue considering priority

Queue

  • print
  • enqueue
  • dequeue
  • front
  • size
  • isEmpty

Stack using native array

  • push
  • pop
  • peek
  • length

Stack not using native array

  • push
  • pop
  • peek
  • length

Deep clone

  • v1 - imperative approach
  • v2 - reduce everything
  • v3 - map arrays, reduce objects
