+ * Exchange sort works by comparing each element with all subsequent elements, + * swapping where needed, to ensure the correct placement of each element + * in the final sorted order. It iteratively performs this process for each + * element in the array. While it lacks the advantage of bubble sort in + * detecting sorted lists in one pass, it can be more efficient than bubble sort + * due to a constant factor (one less pass over the data to be sorted; half as + * many total comparisons) in worst-case scenarios. + *
