有5个zk节点，有1个节点查看状态一直报错： ZooKeeper JMX enabled by default Using config: /home/hadoop/bigdata/zk/bin/../conf/zoo.cfg Client port found: 2181. Client address: localhost. Error contacting service. It is probably not running. 手工重启后，任然是上面的信
We also use a smaller mini-batch size of 256 without any noticeable performance degradation. This is in contrast to CURL and DrQ that both use a larger batch size of 512 to attain more stable training in the expense of computational efficiency.
快速排序 快速排序是比较常用的一种排序方式，通过递归的方法进行排序 首先使用递归方式我们先要解决两个问题：1找到基准条件 2找到递归条件 基线条件为数组为空或只包含一个元素。在这种情况下，只需原样返回数组——根本就不用排序 那么这样我们就会把数组长度小于2的定位我们基
数组中每个元素所在位置右边比它小的元素 int[] nums = { 5, 2, 6, 1 }; var rslt = CountSmaller(nums); foreach (var item in rslt) { Console.Write(item + " "); } private int[] CountSmaller(int[] nums) { if (nums == null || nums.Length == 0) { return new in
A broker is a person or firm who arranges transactions between a buyer and a seller for a commission when the deal is executed. A broker who also acts as a seller or as a buyer becomes a principal party to the deal. Neither role should be confused with th

整型数组arr长度为n(3 <= n <= 10^4)，最初每个数字是<=200的正数且满足如下条件： arr[0] <= arr[1] 2.arr[n-1] <= arr[n-2] arr[i] <= max(arr[i-1], arr[i+1]) 但是在arr有些数字丢失了，比如k位置的数字之前是正数，丢失之后k位置的数字为0。请你根据上述条件， 计算可能有多少种不同
当遇到的问题相当于，求解 prev smaller element ：初始数组从后往前，维护一个单调递增栈 next smaller element： 初始数组从前往后，维护一个单调递增栈
快速排序(Quick Sort)使用分治法策略。它的基本思想是：选择一个基准数，通过一趟排序将要排序的数据分割成独立的两部分；其中一部分的所有数据都比另外一部分的所有数据都要小。然后，再按此方法对这两部分数据分别进行快速排序，整个排序过程可以递归进行，以此达到整个数据变成有序序列。
You are given an integer array nums and you have to return a new counts array. The counts array has the property where counts[i] is the number of smaller elements to the right of nums[i]. Example 1: Input: nums = [5,2,6,1] Output: [2,1,1,0] Explan

Given an array of n integers nums and an integer target, find the number of index triplets i, j, k with 0 <= i < j < k < n that satisfy the condition nums[i] + nums[j] + nums[k] < target. Example 1: Input: nums = [-2,0,1,3], target = 2 Ou

1. 池化层 pooling 特征降维，减少过拟合 1) pooling的目的是 使得每一层smaller and more manageable ， 这是为了有更少的参数数量，来表示输入的这张图 2） 池化操作 只在平面上（actication map）操作，不在depth上操作，所以depth 不变 3） 它降低了采样率 2. max
