Ugly Number III
Write a program to find the n-th ugly number.
Ugly numbers are positive numbers that are divisible by either a, b, or c.
Since the number can be too large, return the actual answer modulo 10^9 + 7
Example 1:
Input:n = 10, a = 2, b = 3, c = 5
Output: 12
Explanation: 2, 3, 4, 5, 6, 8, 9, 10, 12, 14 is the sequence of the first 10 ugly numbers.
Constraints
1 <= n, a, b, c <= 10^91 <= a * b * c <= 10^18

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
Contrary to popular belief, Lorem Ipsum is not simply random text.
>>> a = [1, 2, 3]
>>> a[-1]
