Here is a step-by-step solution in Python:

1. First, we need to handle the special case where `n` is less than or equal to 0. In this case, we return `False` because a power of three cannot be less than or equal to 0.

```python
if n

Here is a step-by-step solution in Python:

1. First, we need to handle the special case where `n` is less than or equal to 0. In this case, we return `False` because a power of three cannot be less than or equal to 0.

```python
if n <= 0:
    return False
```

2. Next, we check if `n` is a power of three. We can do this by repeatedly dividing `n` by 3 as long as it is divisible by 3. If `n` is a power of three, we will eventually get 1.

```python
while n % 3 == 0:
    n /= 3
```

3. Finally, we check if `n` is 1. If it is, that means `n` is a power of three. Otherwise, it is not.

```python
return n == 1
```

Here is the complete function:

```python
def isPowerOfThree(n):
    if n <= 0:
        return False
    while n % 3 == 0:
        n /= 3
    return n == 1
```

This function will return `True` if `n` is a power of three and `False` otherwise.

This function will return `True` if `n` is a power of three and `False` otherwise.

Given an integer n, return true if it is a power of three. Otherwise, return false.An integer n is a power of three, if there exists an integer x such that n == 3x.
