Insertion Sort is a simple, comparison-based sorting algorithm that builds the final sorted array one element at a time. It works by taking each element from the unsorted portion and inserting it into its correct position in the sorted portion by shifting larger elements to the right. This algorithm is efficient for small or nearly sorted datasets but has a time complexity of O(n²) in the worst case. It is stable, in-place, and widely used in practical scenarios where minimal data movement is required.
