Insertion Sort is one of the most important sorting algorithms for beginners because it helps you understand how sorting works internally and builds a strong foundation for advanced algorithms.

Java Program to perform Insertion Sort

The Insertion sort is another simple sorting algorithm, which can be used to sort any linear data structure like an array or linked list.

It is a simple sorting algorithm that builds the final sorted array one item at a time. It is much less efficient on large lists than more advanced algorithms such as quicksort, heapsort, or merge sort.

Insertion sort

  The Insertion sort algorithm views the data in two halves.   The left half of sorted elements and the right half of elements to be sorted.   In each iteration, one element from the right half is taken and added to the left half so that the left half is still sorted.     Insertion sort is of order O(n2)   Here is the implementation of Insertion order logic for sorting an array of…
