A conveyor belt has packages that must be shipped from one port to another within days days.
The i-th package has a weight of weights[i]. Each day, we load packages onto the ship in the order given. We may not load more weight than the maximum weight capacity of the ship.
Return the least weight capacity of the ship that will result in all the packages being shipped within days days.
Example 1:
Input: weights = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10], days = 5
Output: 15
Explanation: A capacity of 15 ships packages in 5 days: [1,2,3,4,5], [6,7], [8], [9], [10].
Example 2:
Input: weights = [3, 2, 2, 4, 1, 4], days = 3
Output: 6
Example 3:
Input: weights = [1, 2, 3, 1, 1], days = 4
Output: 3
1 <= days <= weights.length <= 5 * 10^41 <= weights[i] <= 500
