Using in-place reversal, which swaps the components to put them in the opposite order. Using the Collections interface’s reverse function, which works with lists.
How do you reverse an array without using another array?
In C, these are the steps to reverse an array without requiring another array: Set i=0 to point to the array’s first element, and j=length-1 to refer to the array’s final element. With the condition ij, run a while loop. Inside the loop, swap the array’s ith and jth elements. Increase I and decrease j.
