Explanation: It's possible to divide it into 4 subsets (5), (1, 4), (2,3), (2,3) with equal sums. Note: 1 <= k <= len(nums) <= 16. 0 < nums[i] < 10000. Solution AI检测代码解析 class Solution { public boolean canPartitionKSubsets(int[] nums, int k) { ...
1 <= k <= len(nums) <= 16. 0 < nums[i] < 10000. 这道题给了我们一个数组nums和一个数字k,问我们该数字能不能分成k个非空子集合,使得每个子集合的和相同。给了k的范围是[1,16],而且数组中的数字都是正数。这跟之前那道Partition Equal Subset Sum很类似,但是那道题只让分成两个子集合,所以问...
