Leetcode: 698. Partition to K Equal Sum Subsets Description Given an array of integers nums and a positive integer k, find whether it’s possible to divide this array into k non-empty subsets whose sums are all equal. Example 1: Input: nums = [4, 3, 2, 3, 5, 2, 1], k = 4 ...
Can you solve this real interview question? Two Sum - Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may n

把subsets 分为 过滤后的 新的 k 组; 从最大数字 开始 递归,每次试着把数字放入 subset,更新 subset; 当所有数字都放完之后,成功; 当试完所有可能性后,数字没有放完,失败。 具体看code。 Java Solution: Runtime: 30 ms, faster than 21.47%
subsets[i]-=nums[index]; } }returnres; } } 提交后顺利ac,运行时间858ms。若不优化,则TLE。 看了一下discusscaihao0727mail的解答,总结一下思路:该博主做题的时候没有加nums元素为正数的条件,所以增加了cur_num,针对sum为0的情况,对于更新后的题目可以省去。
