 * The algorithm iterates through the list and inserts each element into its correct

 * 
 * The time complexity of the algorithm is \f$O(n^2)\f$, and in some cases, it
 * can be \f$O(n)\f$.

 * 
 * @details
 * Insertion sort is a simple sorting algorithm that builds the final
 * sorted array one element at a time. It is much less efficient compared
 * to other sorting algorithms like heap sort, merge sort, or quick sort.
 * 
 * However, it has several advantages:
 * - Easy to implement.
 * - Efficient for small data sets.
 * - More efficient than other O(n²) algorithms like selection sort or bubble sort.
 * - Stable: it does not change the relative order of elements with equal keys.
 * 
 * Insertion sort works similarly to how people sort playing cards in their hands.
 * The algorithm iterates through the list and inserts each element into its correct 
 * position in the sorted portion of the array.
 * 
 * The time complexity of the algorithm is \f$O(n^2)\f$, and in some cases, it
 * can be \f$O(n)\f$.
 * 
 * Example execution:
 * 1. Start with the array [4, 3, 2, 5, 1].
 * 2. Insert 3 in its correct position: [3, 4, 2, 5, 1].
 * 3. Insert 2: [2, 3, 4, 5, 1].
 * 4. Continue this until the array is sorted: [1, 2, 3, 4, 5].
