<p>A conveyor belt has packages that must be shipped from one port to another within <code>days</code> days.</p>\n\n<p>The <code>i<sup>th</sup></code> package on the conveyor belt has a weight of <code>weights[i]</code>. Each day, we load the ship with packages on the conveyor belt (in the order given by <code>weights</code>). We may not load more weight than the maximum weight capacity of the ship.</p>\n\n<p>Return the least weight capacity of the ship that will result in all the packages on the conveyor belt being shipped within <code>days</code> days.</p>\n\n<p>&nbsp;</p>\n<p><strong>Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> weights = [1,2,3,4,5,6,7,8,9,10], days = 5\n<strong>Output:</strong> 15\n<strong>Explanation:</strong> A ship capacity of 15 is the minimum to ship all the packages in 5 days like this:\n1st day: 1, 2, 3, 4, 5\n2nd day: 6, 7\n3rd day: 8\n4th day: 9\n5th day: 10\n\nNote that the cargo must be shipped in the order given, so using a ship of capacity 14 and splitting the packages into parts like (2, 3, 4, 5), (1, 6, 7), (8), (9), (10) is not allowed.\n</pre>\n\n<p><strong>Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> weights = [3,2,2,4,1,4], days = 3\n<strong>Output:</strong> 6\n<strong>Explanation:</strong> A ship capacity of 6 is the minimum to ship all the packages in 3 days like this:\n1st day: 3, 2\n2nd day: 2, 4\n3rd day: 1, 4\n</pre>\n\n<p><strong>Example 3:</strong></p>\n\n<pre>\n<strong>Input:</strong> weights = [1,2,3,1,1], days = 4\n<strong>Output:</strong> 3\n<strong>Explanation:</strong>\n1st day: 1\n2nd day: 2\n3rd day: 3\n4th day: 1, 1\n</pre>\n\n<p>&nbsp;</p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>1 &lt;= days &lt;= weights.length &lt;= 5 * 10<sup>4</sup></code></li>\n\t<li><code>1 &lt;= weights[i] &lt;= 500</code></li>\n</ul>\n
