Given an integer n
and an array of integers primes
, return the nth
super ugly number.
Super ugly number is a positive number whose all prime factors are in the array primes
.
The nth
super ugly number is guaranteed to fit in a 32-bit signed integer.
Example 1:
Input: n = 12, primes = [2,7,13,19]
Output: 32
Explanation: [1,2,4,7,8,13,14,16,19,26,28,32] is the sequence of the first 12 super ugly numbers given primes == [2,7,13,19].
Example 2:
Input: n = 1, primes = [2,3,5]
Output: 1
Explanation: 1 is a super ugly number for any given primes.
Constraints:
1 <= n <= 106
1 <= primes.length <= 100
2 <= primes[i] <= 1000
primes[i]
is guaranteed to be a prime number.
- All the values of
primes
are unique and sorted in ascending order.
