The remove$()$ method resizes the array when necessary by removing an item from the array if it exist

Be sure to reuse your solution from Programming Exercise $5\mathrm{.}3$ as your starter file for the arraybag.py file.

In the arraybag.py file define the remove$()$ method in the ArrayBag class by completing the following:

Check the precondition and raise a KeyError if necessary

Precondition: item is in self.

Raises: KeyError if item in not in self.

Postcondition: item is removed from self.

Search for the index of the target item

Shift items to the left of target up by one position

Decrement logical size

Check array memory here and decrease it if necessary

To test your program run the testResize$()$ method in the testbag.py file.

Added $100$ items, length of bag $=100$

Expect $160$ as length of array $=160$

Removed $76$ items, expect $24$ as length of bag: $24$

Expect $80$ as length of array $=80$

Removed remaining items, length of bag $=0$

Expect $10$ as length of array $=10$
