缓存局部性:简单的说是和命中率有关系,分时间局部性和空间局部性 |

很不错,数组的插入和删除理解的重点是在索引 |

删除索引 index 元素时,可在代码中,循环结束后,将 nums 最后位置元素重置为 0,nums[-1] = 0, 使之与图片中的末尾元素无意义概念一致。 另外,插入元素时,Python 代码中,索引是否正确? 我的理解: for i in range(len(nums) - 1, index +1, -1). |

数组中首个元素对应数组的内存地址偏移量是0,所以数组索引从0开始算起,学到了,感谢!!! |

数组遍历 C++ 代码示例,只是 count++,没有遍历数组,是不是本来要写成 count += nums[i]? |

代码示例 应该加一下语言的语法糖写法? 比如 rust 很多情况是不用 for的 根据情况编译后的效率也比for循环高效 虽然有些矛盾。 但是我觉得可以列出两种实现方式, 一个是for 理解原理另一个是如何更简便的写法。 |

作者您好,为什么在这里会强调“相同类型的元素”,而在下一章链表中却没有强调同类型呢? |

“数组有多种初始化写法。根据实际需要,选代码最短的那一种就好。” k神,个人感觉这句话有点奇怪, |

您好还是不太理解c++数组删除那块,我知道有效长度-1之后最末尾的元素可以忽略掉(无意义),可是这在源代码中没有体现,请问这该如何实现呀?第二个问题是在插入的时候不应该先判断是否满数组再扩容吗?感谢解答 |

佬,删除元素那边是不是要把length-1啊,我看的是Java代码,如果不减的话最后一位元素是重复的吧 |
