📌 What is Insertion Sort?
Insertion Sort is a simple sorting algorithm that builds the sorted array one element at a time. It works by taking an element from the unsorted part, comparing it with previous elements, and placing it in its correct position.

📌 Time Complexity:

Best Case: O(n) (Already Sorted)
Worst Case: O(n²) (Reversed Order)
Average Case: O(n²)
