f(x,y) in Interval

Let

$$f(x,y)=5^x\cdot 3^y$$

Given an interval $[L,R]$ and some integer $N$. Write a function, get_possible_values, that returns all positive integer pairs $(x,y)$ such that $f(x,y)\in[L,R]$ and $x,y\lt N$.

Example:

Input:

L = 0
R = 1
N = 50

Output:

get_possible_values(L, R, N) -> [[0,0]]

Since $f(0,0)=1\in [0,1]$
