**Fibonacci numbers**, commonly denoted as $Fn$, form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from $0$ and $1$. $F(0) = 0, F(1) = 1$ & $F(n) = F(n-1) + F(n-2)$ **e.g.** $0, 1, 1, 2, 3, 5, 8, 13,...$ Write a program to find out $F(N-1)* F(N+1) - F(N)^2$ . ###Input: - The first line contains an integer
