# BigCodeBench/21
Implement a file **`solution.py`** that completes the function below. Keep the given name and signature; define `task_func` at module level.
Allowed libraries: `psutil`, `platform`.
```python
import psutil
import platform
def task_func():
"""
Obtain system details, including operating system, architecture, and memory usage.
This function gathers information about the system's operating system, architecture,
and memory usage. It calculates the percentage of used memory by comparing the total
and currently used memory. The gathered details are then returned in a dictionary
format with specific keys for each piece of information.
Returns:
dict: A dictionary containing:
- 'OS': Operating System name (e.g., 'Windows', 'Linux').
- 'Architecture': System architecture (typically first item from platform.architecture(), e.g., '64bit').
- 'Memory Usage': Formatted string representing the percentage of memory currently in use,
calculated as (used memory / total memory) * 100.
Requirements:
- platform
- psutil
Examples:
>>> system_info = task_func()
>>> isinstance(system_info, dict)
True
>>> 'OS' in system_info
True
>>> 'Architecture' in system_info
True
>>> 'Memory Usage' in system_info
True
"""
