For a positive integer `n` , find the value of `(1-i)^n(1-1/i)^ndot`

Explanation

To solve the problem of finding the value of \((1-i)^n(1-\frac{1}{i})^n\) for a positive integer \(n\), we can follow these steps:

### Step 1: Simplify \(1 - \frac{1}{i}\)

We start by simplifying the term \(1 - \frac{1}{i}\):
\[ 1 - \frac{1}{i} = 1 - (-i) = 1 + i \]
