# 508: DS-1000 Task

## Prompt
Problem: 
Here is a rather difficult problem.
I am dealing with arrays created via numpy.array(), and I need to draw points on a canvas simulating an image. Since there is a lot of zero values around the central part of the array which contains the meaningful data, I would like to "truncate" the array, erasing entire columns that only contain zeros and rows that only contain zeros.
So, I would like to know if there is some native numpy function or code snippet to "truncate" or find a "bounding box" to slice only the part containing nonzero data of the array.
(since it is a conceptual question, I did not put any code, sorry if I should, I'm very fresh to posting at SO.)
TIA!

A:
<code>
import numpy as np
A = np.array([[0, 0, 0, 0, 0, 0, 0],
           [0, 0, 0, 0, 0, 0, 0],
           [0, 0, 1, 0, 0, 0, 0],
           [0, 0, 1, 1, 0, 0, 0],
           [0, 0, 0, 0, 1, 0, 0],
           [0, 0, 0, 0, 0, 0, 0],
           [0, 0, 0, 0, 0, 0, 0]])
</code>
result = ... # put solution in this variable
BEGIN SOLUTION
<code>

## What to do
- Edit `solution/solution.py` so the code passes the DS-1000 tests.
- Do not access the internet or install new packages; required libraries are preinstalled in the Docker image.
- Run tests locally via `bash tests/test.sh`.

## Notes
- Keep the variable names/signatures implied by the prompt/code_context.
- The evaluator uses the original DS-1000 `code_context` (`test_execution` / `test_string`).
