func nthSuperUglyNumber(n int, primes []int) int {dp := make([]int, n+1)m := len(primes)pointers := make([]int, m)nums := make([]int, m)for i := range nums {nums[i] = 1}for i := 1; i <= n; i++ {minNum := math.MaxInt64for j := range pointers {minNum = min(minNum, nums[j])}dp[i] = minNumfor j := range nums {if nums[j] == minNum {pointers[j]++nums[j] = dp[pointers[j]] * primes[j]}}}return dp[n]
}func min(a, b int) int {if a < b {return a}return b
}
