Problem
Implement an ArrayList via an ops list: ['append', val] adds to the end, ['get', index] returns element at index, ['size'] returns current count, ['remove', index] deletes element at index. Return the list of return values excluding None: only get, size, and remove operations contribute to output (append returns nothing).
Summary
Build your own resizable list with no help from the standard library.
