This element neither has attached source nor attached Javadoc and hence no Javadoc could be found Eclipse有直接查看Java文档和类库源码的功能,不过得手工添加才行,下面对如何在Eclipse中添加java文档和类库源码进行总结. 1. Window->Pereferences...打开参数选择对话框,展开Java节点,单击"Installed JREs",此时右边窗口会显示已…

Find Peak Element A peak element is an element that is greater than its neighbors. Given an input array where num[i] ≠ num[i+1], find a peak element and return its index. The array may contain multiple peaks, in that case return the index to any one…

Find the kth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element. For example,Given [3,2,1,5,6,4] and k = 2, return 5. 思路: 堆.讲解:二叉堆 class Solution { public: //新插入i结点 其父节点为(i…

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. Solution 1: 使用map计数 class So…

Given an array and a value, remove all instances of that value in place and return the new length. The order of elements can be changed. It doesn't matter what you leave beyond the new length. Solution 1: int removeElement(vector<int>& nums, int…

A peak element is an element that is greater than its neighbors. Given an input array where num[i] ≠ num[i+1], find a peak element and return its index. The array may contain multiple peaks, in that case return the index to any one of the peaks is fi…

1.依赖安装 本例中,使用render-content进行树节点内容的自定义,因此需要支持JSX语法.(见参考资料第3个) 在Git bash中运行一下指令 cnpm install\ babel-plugin-syntax-jsx\ babel-plugin-transform-vue-jsx\ babel-helper-vue-jsx-merge-props\ babel-preset-es2015\ --save-dev  2.常用属性 Attributes des type defaul…
