# 171: DS-1000 Task

## Prompt
Problem:
I have a dataFrame with rows and columns that max value is 2.
   A  B  C  D
0  1  2  0  1
1  0  0  0  0
2  1  0  0  1
3  0  1  2  0
4  1  1  0  1


The end result should be
   A  D
1  0  0
2  1  1
4  1  1


Notice the rows and columns that had maximum 2 have been removed.


A:
<code>
import pandas as pd


df = pd.DataFrame([[1,2,3,1],[0,0,0,0],[1,0,0,1],[0,1,2,0],[1,1,0,1]],columns=['A','B','C','D'])
</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`).
```
