Output: false Explanation: The array cannot be partitioned into equal sum subsets. Solution 0-1背包问题。 dp[j] = dp[j] || dp [j - n]; Code classSolution{public:boolcanPartition(vector<int>& nums){intsum =0;for(intn : nums) sum += n;if(sum %2!=0)returnfalse; sum /=2;re...
int sum = Arrays.stream(nums).sum(); // 场景1:和为奇数不能均分 if (sum % 2 == 1) { return false; } int target = sum / 2; int n = nums.length; boolean[][] dp = new boolean[n + 1][target + 1]; dp[0][0] = true; for (int i = 1; i <= n; i++) { for (...
Input: [1, 2, 3, 5] Output:falseExplanation: The array cannot be partitioned into equal sum subsets. Backpack problem: dp[i][j] means if the first i elements can sum up to value j dp[i][j] = dp[i-1][j] || (j>=nums[i-1] && dp[i-1][j-nums[i-1]]) the result is...
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
其实是找有没有sub array的数字和是sum/2. Thus for the other half, sum must be sum/2. Let dp[i] denotes if there is subarray sum equal to j. dp[0] = true. Then for each num in nums, dp[num] would be true. Thus for i, check if dp[i-num], if dp[i-num] is true. Then...
Explanation: The array cannot be partitioned into equal sum subsets. 假设有一个全为正整数的非空数组,将其中的数字分为两部分,确保两部分数字的和相等。 思路和代码 这和0-1背包问题是完全一样的,01背包问题是指假设有n个物品,每个物品中为weight[i],假设背包的承重为k,问如何选择物品使得背包中的承重最...
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] 。 示例2: 输入:nums = [1,2,3,5]输出:false解释:数组不能分割成两个元素和相等的子集。
