# Description
From the [Esolangs wiki,](https://esolangs.org/wiki/Fractran)
In Fractran,
- a program consists of a finite list of positive, rational numbers.
- The input to a program is a positive integer n.
- The list is then searched in order, for a rational number \$p/q\$ such that \$n×p/q\$ is an integer.
- Then n is replaced by \$n×p/q\$ and the search is restarted from the beginning of the list.
- The program halts when no such number \$p/q\$ can be found, and the final n becomes the output from the program.
- Output the final value of \$n\$.
Your task is to implement an interpreter for this language.
# Input
You are to take two inputs:
- \$n\$, an integer
- \$A\$, an array of fractions, which may be taken as a list of pairs, or in the rational datatype of your language.
# Output
A single integer, the final value of \$n\$.
# Test Cases
Formatted as
