1182E · Product Oriented Recurrence

Problem: Let $f_{x} = c^{2x-6} \cdot f_{x-1} \cdot f_{x-2} \cdot f_{x-3}$ for $x \ge 4$.

You have given integers $n$, $f_{1}$, $f_{2}$, $f_{3}$, and $c$. Find $f_{n} \bmod (10^{9}+7)$.

Input Format: The only line contains five integers $n$, $f_{1}$, $f_{2}$, $f_{3}$, and $c$ ($4 \le n \le 10^{18}$, $1 \le f_{1}$, $f_{2}$, $f_{3}$, $c \le 10^{9}$).

Output Format: Print $f_{n} \bmod (10^{9} + 7)$.

Note: In the first example, $f_{4} = 90$, $f_{5} = 72900$.

In the second example, $f_{17} \approx 2.28 \times 10^{29587}$.
