Leetcode 368. Largest Divisible Subset Given a set of distinct positive integers, find the largest subset such that every pair (Si, Sj) of elements in this subset satisfies: Si % Sj = 0 or Sj % Si = 0. If there are multiple solutions, return any subset is fine. 题目意思也很简单,给...
https://discuss.leetcode.com/topic/46161/a-general-approach-to-backtracking-questions-in-java-subsets-permutations-combination-sum-palindrome-partitioning/2 里面比较难想的部分(对于我这种只捡easy模式的题目做的算法小白)是循环里面的递归,每次退栈的时候,会从cur中remove一个元素出来,然后i要加1,继续循环!!

Problem 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: Each of the array element will not exceed 100.
Unlike the UnicodeBlock subsets defined in the Character.UnicodeBlock class, these constants do not directly correspond to Unicode code blocks.
