Can you solve this real interview question? Partition to K Equal Sum Subsets - Given an integer array nums and an integer k, return true if it is possible to divide this array into k non-empty subsets whose sums are all equal. Example 1: Input: num
nums, returnif you can partition the array into two subsets such that the sum of the elements in both subsets is equal orfalseotherwise. 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...
看了hint后想到的是创建一个大小为k的int[] subsets数组,然后顺序考虑每一个nums中元素,对于每一个元素考虑将其加到subsets中的每一个子集合中。对于nums中每一个数,均有k种选择,此种解法的时间复杂度为O(k^n)。 此种算法可进行一些优化(条件见代码),代码如下 ...
