To check if a number is a power of two, you can use the bitwise AND operator to compare the number with the number one less than itself. If the result is zero, the number is a power of two. Here's an example code snippet in Python:

```python
def is_power_of_two(n):
    return (n != 0) and (n & (n - 1) == 0)
```



The function takes an integer `n` as input and returns `True` if `n` is a power of two, and `False` otherwise.
