Solve the programming task below in a Python markdown code block.
Given two arrays of integers `m` and `n`, test if they contain *at least* one identical element. Return `true` if they do; `false` if not.

Your code must handle any value within the range of a 32-bit integer, and must be capable of handling either array being empty (which is a `false` result, as there are no duplicated elements).
Also feel free to reuse/extend the following starter code:
```python
def duplicate_elements(m, n):
```
