swift-leetcode

前言

本仓库是我使用swift刷LeetCode的记录。

作为一名应届生，刷题是提高自己算法能力的一种很有效的方法。LeetCode的题目描述相对于oj题目来说十分简洁，而且并不需要自己接收参数，对于刷题的新手来说十分友好。

TODO

1. 完善题目注释
2. 改善README的题目列表
3. 新增一些常见的算法模板

模板

排序模板

1. 归并排序
2. 快速排序
3. 堆排序的

排序

树遍历模板

1. 层序遍历
2. 前序遍历递归和非递归
3. 中序遍历递归和非递归
4. 后续遍历递归和非递归
5. 垂序遍历

树遍历(1-4)

链表模板

1. 不使用栈的方式翻转链表
2. 合并两个有序链表

题目
