【题目】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. The array size will not exceed 200. Example 1: ...
For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1. 【解答】checkBalanced 方法用来递归检查是否平衡的,返回树高度,偷了个巧,如果发现不平衡抛出 TreeUnbalancedException 异常: 代码语言:javasc...
Given an array of size n, find the majority element. The majority element is the element that appears more than ⌊ n/2 ⌋ times. You may assume that the array is non-empty and the majority element always exist in the array.

This problem actually has the same solution as the above one. What is difference is that it may need O(n) complexity because of the duplication condition. If there are a lot of duplicate value, it will always run left++, then it will only need step by step working. 1 public int fin...
