### 华为OD统一考试A卷+B卷 新题库说明 ###

2023年5月份，华为官方已经将的 2022/0223Q(1/2/3/4)统一修改为OD统一考试（A卷）和OD统一考试（B卷）。  
你收到的链接上面会标注A卷还是B卷。请注意：根据反馈，目前大部分收到的都是B卷。但是仍有概率抽到A卷。  
**A卷对应2023的新题库（2022Q4 20223Q1）** **B卷对应20022部分考题以及新出的题目**

### 面试者信息 ###

*  语言：java
 *  工作经验：半年
 *  目标部门：电商业务

### 面试流程 ###

总体流程很快，HR很负责经常帮忙催进度，从笔试到发offer差不多两周。

*  **笔试**
 *  **HR资面**
 *  **技术面**
 *  **一面**
 *  **二面**
 *  **综面**

#### 笔试 ####

*  笔试得分：395
 *  难度：不高

##### 题目详情 #####

1.  第一、第三题：dp和哈希表，100%通过。第一题题目一开始没看懂意思，看了挺久。
2.  第二题：为新员工找友好度最高的座位，数组表示座位情况，如11101211100111211，0为空，1为老员工，2为墙壁。空座位左右连续老员工数量等于该座位友好度，遇到墙壁则好友度清空。
    
     *  时间复杂度O(n)，有一个用例超时了，95%。
     *  初始思路是遍历数组，遍历到0时查找左右友好度情况，但是会有重复计算的问题，想着优化一下。
     *  改为遍历一遍数组，遍历的同时维护左友好度和右友好度以及当前是否已记录座位。初始状态未记录座位，增加左友好度，当遇到座位时判断是否已记录座位，已记录时计算一次结果（左+右），未记录时更新状态。遇到老员工时根据是否已记录座位增加左/右友好度，遇到墙时计算结果+清除友好度。

### 性格测试（综合测试） ###

按照 HR 给的注意事项选就行，注意前后选择的一致性，选择正向的答案。

### 面试经历 ###

*  HR 资面：简单聊了一会儿，HR 说西安和深圳都能去，西安比较缺人。我觉得有点远，想去深圳，HR 说面试完再确定也可以。最后也去的深圳。
 *  离职原因：期望工作地，期望薪资。
 *  最近情况：投简历、复习、面试。

#### 技术面 ####

技术面都是技术问题 + 编程题，技术问题答得一般般，面试当天是周五，上午一面晚上二面，那周前几天已经面试了 10 场没啥状态，有点开摆了，编程题都 AC。

*  编程题是分享屏幕，然后用自己电脑上的 IDE 编写，写完面试官会给用例。

##### 一面 #####

*  八股问的都不是很深，记不太清了，各个方面有提到，会的就简单聊一下，不会的就换其他问题。
 *  聊项目，业务 + 技术。
 *  Java 集合。
 *  SpringBoot 自动配置原理。
 *  MySQL 索引原理，工作中数据库优化的案例。
 *  Redis 数据类型和原理。
 *  编程题：找出有效 MAC 地址，通常表示为 12 个 16 进制数，如：00-16-EA-AE-3C-40。给一串字符串， 如 00-16:aA-FE:3C-40-11-99-AA-Z，找出其中所有的有效 MAC 地址，不区分大小写以及 : 和 -。

解法：MAC 地址有固定长度，思路是滑动窗口判断当前部分是否为有效 MAC 地址。首先先对原字符串 LowerCase()，再将 : 替换为 -，方便验证。验证的地方主要是窗口内是否为 12 个 16 进制数，并且通过 - 连接。

### 二面 ###

#### 编程题 ####

面试官先询问是否做过该题，回答没有做过原题，但有一些思路。在讲述思路后，面试官确认无问题后开始写代码。

#### 项目经验 ####

*  谈论了个人项目经验。
 *  面向对象和面向过程的理解。
 *  平时使用的JDK版本（JDK8），并讨论了JDK8和旧版本之间的不同之处，如集合优化、JVM和新特性等。
 *  讨论了lambda表达式的优缺点，如语法精简和不易调试等。
 *  泛型的用处、应用、原理以及程序在运行时如何知道是哪种类型。
 *  线程池的7个参数，分析线程池工作时各参数变化情况（初始线程池容量x，最大容量y，队列长度z，来了n个任务，讲一下会发生的情况）。

#### 技术知识 ####

*  Spring AOP的原理和应用。
 *  MySQL explain。
 *  单元测试。
 *  设计模式的应用和了解的种类。

#### 编程题 ####

给一个01矩阵，找其中1表示的最大面积正方形。

例如：

0 0 1 0
    1 1 1 0
    1 1 0 0

解法：遍历矩阵，找到为1的点后以这个点作为正方形的左上角，扩展正方形，同时计算最大面积。

### 综面 ###

面试官表示他们部门招人比较看重编程能力

问简历上的项目，更侧重对业务的提问  
日常学习方式（看书、刷题），为什么要刷题，觉得有用吗  
上一段工作中的收获

## ACM输入输出模式 ##

如果你经常使用**Leetcode**,会知道**letcode**是不需要编写输入输出函数的。但是华为OD机考使用的是 **ACM 模式**，需要手动编写输入和输出。

所以最好在牛-客上提前熟悉这种模式。例如C++使用`cin/cout`,python使用`input()/print()`。JavaScript使用node的`readline()`和`console.log()`。Java 使用`sacnner/system.out.print()`

## 机考代码查重 ##

华为OD机考完成之后，官方会进行代码查重。**华为 od 机考确实有很大的概率抽到原题**。如果碰到了题库中的原题，一定不要直接使用题解中的代码，尤其是变量名，一定要修改，可以改成毫无意义的单词。除了变量名之外，代码的组织结构和逻辑一定要进行改变，这就要求在日常的刷题中，提前编写好属于自己的代码。
