Solution

class Solution:
    def check(self, nums, threshold, val):
        s = 0
        for num in nums:
            s += (num + val - 1) // val
        return s <= threshold

    def smallestDivisor(self, nums: List[int], threshold: int) -> int:
        l = 1
        r = sum(nums)

        while l < r:
            m = (l + r) // 2

            if self.check(nums, threshold, m):
                r = m
            else:
                l = m + 1

        return l
