This is the similar problem with "31. Next Permutation", the differences are: 1. 31 don't care about whether the "next" is larger or not, but 556 care, 556 need the next is larger than it. 2. 31's input is an array, while 556
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。

在确保kafka、zookeeper 版本正确，并且启动正常的情况下， 可以自己看看配置的zookeeper路径下有没有kafka的元数据。 我遇到的原因是 kafka的server.properties 配置文件写的 127.0.0.1:2181/kafka 然后使用命令的时候写了 –zookeeper 127.0.0.1:2181 改成下面就可以了 –zookeepe

kafka版本：2.11-2.0.0 在创建 Topic 时，报出以下错误： 问题是我有 3 台broker，副本设为 2 不应该会大于 broker 数量。我先检查 3 台 broker 是否已经成功启动，到 zookeeper 查看： 3 台 broker 是成功启动的，那么问题就是 zookeeper中 kafka 的地址没写对，正确的应该是带上 kafka
在使用TensorFlow 1.X版本的estimator的时候经常会碰到类似于ValueError：GraphDef cannot be larger than 2GB的报错信息，可能的原因是数据太大无法写入graph。 一般来说，常见的数据构建方法如下: def input_fn(): features, labels = (np.random.sample((100,2)), np.random.sampl
thinking: 1.Fibonacci ，那就得把Fibonacci数表达出来；method_1：用递归;method_2: 用数字相加；2.想得到最小步数，就得求出最接近的Fibonacci数；method_1: 通过递归求出，通过判断递归出数的值，与输入值比较，锁定左右两值；method_2: 通过两变量相加等于较大值较小值等于原来较大值，较大值大于
问题背景与现象 在使用Kafka客户端命令创建Topic时，发现Topic无法被创建。 kafka-topics.sh --create --replication-factor 2 --partitions 2 --topic test --zookeeper 192.168.234.231:2181 提示错误replication factor larger than available brokers。 具体如下： Error wh

Given two arrays, write a function to compute their intersection. Example 1: Input: nums1 = [1,2,2,1], nums2 = [2,2]Output: [2,2] Example 2: Input: nums1 = [4,9,5], nums2 = [9,4,9,8,4]Output: [4,9] Note: Each element in the result should appear as many
问题描述： 在编译内核模块驱动时，如果出现如下警告信息： warning: the frame size of 1040 bytes is larger than 1024 bytes。主要是因为内核中设置了堆栈报警大小，其默认为1024bytes。我们主要将其修改为4096既可以消除告警信息。 如果解决： （1）make menuconfig （2）kern
