旧城等待， 2023-09-27 22:53 55阅读 0赞

### **华为机试题库已于5月10号由2022Q4 A卷 切换 为2023 B卷**  ###

#### **各位同学如果收到的是B卷则刷下面的题，如果收到的是A卷则去A卷区刷题** ####

#### **A卷区地址 →→→ [华为OD机试真题2022Q4 A卷（JAVA&JS）][OD_2022Q4 A_JAVA_JS]** ####

#### 华为机试有三道题目，第一道和第二道属于简单或中等题，分值为100分，第三道为中等或困难题，分值为200分。总分为**400**分，**150分钟**考试时间。**之前通过为****150分****，现在好像****分数提高****了，大家不要太大意，一定要多刷题，争取拿高分，毕竟****分数越高评级越高，工资也就越高****。OD的工资待遇还是很可观的****15K-30K\*14-16****，希望大家努力（肺腑之言）** ####

#### **即将考试的同学不要慌，华为机试的题目的算法思想其实都差不多，只要认真刷过题的都没有问题** ####

#### 因为是刚切的题库，目前考试的同学较少，后期会不间断更新题目和**【满分】**答案，大家别急，敬请期待。。。 ####

#### 机试过了的同学，不要放松，一面二面还有算法题，**当面手撕**，除了考验大家的**算法思想**外，还考验大家的**心态**，加油！！！ ####

#### 根据目前看到的机试试卷，应该有不少题目来自2022年的考卷；部分题我已经筛选出来了，其他的大家可以先看看 →→→ **[华为OD机试2022卷][OD_2022]** ####

#### 这里为大家准备了算法中常用的一些知识点。 →→→ [算法常用知识点][Link 1] ####
