Reverse Array Without rev

EasyPython

Problem

Write code to reverse an array without using a rev function.

Implement def reverse_array(arr):. The function must reverse the input list in place and return the reversed list. Use only basic array operations and do not call Python's built-in reverse() or create a second array.

Constraints

0 <= arr.length <= 1000
-10^9 <= arr[i] <= 10^9
The input list must be modified in place
Do not call reverse(), reversed(), or any equivalent reverse function

Function Signature

def reverse_array(arr):
