[leetcode]416. Partition Equal Subset Sum Given a non-empty array containing only positive integers, find if the array can be partitioned into two subsets such that the sum of elements in both subsets is equal. 给定一个非空数组,是否能把数组划分为两个和相等的子集。 Not......
第一行 nums[0] 那一行,如果选择了 nums[0],那么我们可以构造一个子数组使得他的和 = 1,所以在 [1, 1] 那个位置可以填 true。这一行剩下的部分,因为 1 已经选择过了同时无论选不选1,都无法构造成一个更大的 sum,所以 nums[0] 那一行后面全是 false。 第二行 nums[1] 那一行,1 的位置可以继承...
Example 1: Input:nums = [1,5,11,5]Output:trueExplanation:The array can be partitioned as [1, 5, 5] and [11]. Example 2: Input:nums = [1,2,3,5]Output:falseExplanation:The array cannot be partitioned into equal sum subsets. ...
https://leetcode.cn/problems/partition-equal-subset-sum 给你一个 只包含正整数 的 非空 数组 nums 。请你判断是否可以将这个数组分割成两个子集,使得两个子集的元素和相等。 示例1: 输入:nums = [1,5,11,5] 输出:true 解释:数组可以分割成 [1, 5, 5] 和 [11] 。
leetcode416. Partition Equal Subset Sum 题目要求 Given a non-empty array containing only positive integers, find if the array can be partitioned into two subsets such that the sum of elements in both subsets is equal. Note: 1.Each of the array element will not exceed 100....
如果数组长度为N,目标sum(即总和的一半)是M,由于全部是正整数,那么在递推过程中涉及到的和只可能是0到M,于是可以用一个 N x (M+1) 的表格tab记录结果。其中tab[i][j]表示在第0至i个数中,是否存在和为j的子集。时间复杂度为O(MN),因为每次递推只需要用到上一行的结果,则空间复杂度可以优化到O(M)...
Can you solve this real interview question? Partition Equal Subset Sum - Given an integer array nums, return true if you can partition the array into two subsets such that the sum of the elements in both subsets is equal or false otherwise. Example 1
