HDU 3473 Minimum Sum partition tree

Given a sequence, each time we ask for an interval, We need to select a number. The sum of the distances of all numbers in the interval is the smallest, and the sum of the minimum and From the absolute value inequality, we can see that when the number we choose is the median, the distance and the minimum are converted to the K smaller range. However, this question is the minimum

Leetcode 416. Partition Equal Subset Sum

Given a non-empty array containing only positive integers, find if the array can is partitioned into Subsets such the sum of elements in both subsets is equal.Note: Each of the array element would not be exceed 100. The array size would not be exceed 200. Example 1:Input: [1, 5, one, 5]output:trueexplanation:the array can be partitioned as [1, 5, 5] and [11].Example 2:Input: [1, 2, 3, 5]output:falseexplanation:the array cannot is par

Algorithm-partition Equal subset Sum (Dynamic planning)

only one-dimensional arrays are used.Which means:We define a DP array to indicate whether a number is the same as any of the nums of an array, for example, dp[2] to indicate whether 2 is the and of any of the nums's sets, and if so, that is true, otherwise false. So we end up looking at DP[SUM/2] (sum of the nums for the array) is true. But how do we get this DP array?First, we get DP[
