2023年11月份，华为官方已经将华为OD机试（A卷/B卷）切换为 C卷/D卷。

目前正在考的是C卷，按照华为OD往常的操作，C卷题目是由往年真题（A卷/B卷）+全新题目组成，也就是说C卷和D卷还会考到A卷和B卷的题目的，比例大概是1道新题、2道旧题的样子。

**2023年11月份之后，很多小伙伴收到的是C卷，那么恭喜你看到本文了，抓紧刷题吧。C卷新题库正在更新中**。

**华为机试有三道题，第一道和第二道属于简单题，分值为100分，第三道为困难题，分值为200分，总分400分，150分钟考试时间**。

#### 一、逻辑分析 ####

#### 二、字符串 ####

#### 三、数据结构 ####
