最近有朋友问我怎么没有更新文章了,因为最近有空的时候都在刷 LeetCode,零零星星刷了快 2 个月了,也累积了不少题目了,所以最近打算把做的几百道题归类,总结一下。所有题目的代码在github.com/halfrost/Le…,每道题都有测试用例和测试代码。 Linked List 的 Tips: 巧妙的构造虚拟头结点。可以使遍历处理逻辑更...
ArrayList和LinkList的描述,下面说法错误的是()。 A. LinkedeList和ArrayList都实现了List接口 B. ArrayList是可改变大小的数组,而LinkedList是双向链接串列 C. LinkedList不支持高效的随机元素访问 D. 在LinkedList的中间插入或删除一个元素意味着这个列表中剩余的元素都会被移动;而在ArrayList的中间插入或删除一个元素...
走访Linked List 时考虑进位 给出两个 非空 的链表用来表示两个非负的整数。其中,它们各自的位数是按照 逆序 的方式存储的,并且它们的每个节点只能存储 一位 数字。 如果,我们将这两个数相加起来,则会返回一个新的链表来表示它们的和。 您可以假设除了数字 0 之外,这两个数都不会以 0 开头。
Explanation: There is no cycle in the linked list. 1. 2. 3. 4. 5. 第一次做; 快慢指针; 理解初始化和循环终止条件; 快指针每次移动两步, 判断条件是固定的if(fast==null || fast.next==null), 找链表中点的时候也用到了快慢指针 时间复杂度O(N) ...

The list elements are placed in a vector, which is why they can be accessed directly, where each element knows the index of the element before and after it, as well as the data contained at that index. This indirection makes it easy to implement the list safely in Rust, because the tra...
