In this tutorial, we demonstrate a simple Python function to reverse an array in-place. The function reverse_array takes a list a as input and swaps elements symmetrically from the start and end, moving towards the center. By iterating only up to half the length of the array, it efficiently reverses the elements with minimal operations. This approach modifies the original array without using extra space, making it an optimal solution for reversing arrays. We then test the function with an example array [1, 2, 3, 4, 5] to show the original and reversed arrays in the output.
