For today’s algorithm, I picked the binary search which is one of the most commonly asked topics in technical interviews. The problem named binary search from LeetCode will be used to explain this concept:

Given a sorted (in ascending order) integer array nums of n elements and a target value, write a function to search target in nums. If target exists, then return its index, otherwise return -1.

Binary Search in JavaScript

Divide and conquer algorithm. A binary search is a searching algorithm for finding an item from a sorted list of items. It works by repeatedly dividing in half the portion of the list that could contain the item until you’ve narrowed down the possible locations to just one. As compared to linear, binary search is much faster with Time Complexity of O(logN) whereas the linear search algorithm works in O(N) time complexity. The implementation of binary search can be done iteratively or recursively.

Deletion in Binary Search Tree with JavaScript

Prerequisite: Binary Search Tree In JavaScript. Deletion in Binary Search Tree with JavaScript. Deletion in binary search tree can be tricky, since we’re not working with just leafs but having to restructure all of a node’s children. Node to be deleted is leaf. To delete a leaf node, simply remove it from the tree. Since it was a leaf node we deleted it from the tree without making any other changes.

Learn Arrays And Array Methods in JavaScript

In JavaScript, an array is a data structure that contains list of elements which store multiple values in a single variable. The strength of JavaScript arrays lies in the array methods. Array methods are functions built-in to JavaScript that we can apply to our arrays — Each method has a unique function that performs a change or calculation to our array and saves us from writing common functions from scratch. In this video we are going to learn arrays and array methods like sort(), reverse(), join(), split(), pop(), push(), shift(), unshift(), toString(), delete array, etc.......

Finding Common Ancestor, Binary Search Tree, JavaScript

Finding the common ancestor in a binary search tree, in Javascript. Understand the recursive stack values during LCA. Finding the common ancestor in a binary search tree in Javascript is not rocket science. However, many a time, newbies struggle in understanding how the values flow within the recursive calls. This post will help you understand the steps, and output involved at each stage of the algorithm.
