Insertion Sort

+
+
+
+

Insertion Sort is a simple and intuitive comparison-based sorting algorithm. It 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. The algorithm works by dividing the array into a sorted and an unsorted part. Initially, the sorted part contains only the first element, and the unsorted part contains the rest of the elements. It then takes elements from the unsorted part one by one and inserts them into the correct position in the sorted part.
