Insertion Sort
Insertion sort is a technique of sorting wherein you build a sorted array from an unsorted one by picking wrongly placed elements from the unsorted part of the array and placing them at the correct position in the sorted part.
What is insertion sort?
In this technique of sorting, we basically select an element of the array at a...

Binary Search
Binary Searching algorithm is used to search for an element in a sorted array. It involves dividing an array into halves until the element is finally found.

Binary Tree Traversal Methods
In this article I'm gonna talk about the ways of traversal we can perform on Binary Trees.
A node of a binary tree primarily consists of three components -
it's own data (D)
It's left child (L)
