Use a sorting algorithm like bubble sort or quicksort to arrange elements in ascending order.

• Use a sorting algorithm like bubble sort, quicksort, or merge sort to rearrange elements in ascending order.

• For example, you can implement bubble sort to compare adjacent elements and swap them if they are in the wrong order.
