你已经掌握了排序算法的奥秘了，那么就来一场试炼罢。

LeetCode 148. Sort List

1 Selection sort

创建一个 sentinel node，每次选出最大的 node，append 到 sentinel 后面。

class Solution {\n\n    public ListNode sortList(ListNode head) {\n        return selectionSort(head);\n    }\n\n    private static ListNode selectionSort(ListNode head) {\n        ListNode sentinel = new ListNode(0, null);\n        while (head != null) {\n            ListNode largestPrev = findLargestPrev(head);\n            ListNode largest = largestPrev.next;\n\n            if (largest == head) {\n                head = head.next;\n            }\n            largestPrev.next = largest.next;\n            largest.next = sentinel.next;\n            sentinel.next = largest;\n        }\n        return sentinel.next;\n    }\n\n    /** return the previous node of the largest node */\n    private static ListNode findLargestPrev(ListNode head) {\n        ListNode largestPrev = new ListNode(0, head);\n        ListNode currentPrev = largestPrev;\n        while (currentPrev.next != null) {\n            if (currentPrev.next.val > largestPrev.next.val) {\n                largestPrev = currentPrev;\n            }\n            currentPrev = currentPrev.next;\n        }\n        return largestPrev;\n    }\n}\n

时间复杂度 $O(N^{2})$ ，空间复杂度 $O(1)$ ，不出意外的 TLE。

2 Insertion sort

数组的 insertion sort 是从头开始遍历，如果比左边小就向左交换位置。对于 SLList，依然是创建一个 sentinel node，从 head 节点开始一个一个插入 sentinel 之后，若比后面节点大则向右交换。

class Solution {\n\n    public ListNode sortList(ListNode head) {\n        return insertionSort(head);\n    }\n\n    private static ListNode insertionSort(ListNode head) {\n        ListNode sentinel = new ListNode(0, null);\n        while (head != null) {\n            ListNode temp = head;\n            head = head.next;\n            temp.next = sentinel.next;\n            sentinel.next = temp;\n            swapHelper(sentinel);\n        }\n        return sentinel.next;\n    }\n\n    /** swap first node of sorted list rightwards while larger than right */\n    private static void swapHelper(ListNode sentinel) {\n        ListNode prev = sentinel;\n        ListNode newly = sentinel.next;\n\n        while (newly.next != null && newly.val > newly.next.val) {\n            prev.next = newly.next;\n            newly.next = newly.next.next;\n            prev.next.next = newly;\n\n            prev = prev.next;\n        }\n    }\n}\n

时间复杂度 $O(N^{2})$ ，空间复杂度 $O(1)$ ，又是令人欣慰的 TLE。但是这个指针操作比上一个要优雅多了。

3 Mergesort

Divide and conquer. Use top-down mergesort.

class Solution {\n\n    public ListNode sortList(ListNode head) {\n        if (head == null) return null;\n        return mergesort(head);\n    }\n\n    /** recursively split and merge */\n    private static ListNode mergesort(ListNode head) {\n        if (head.next == null) return head;\n        ListNode mid = split(head);\n        ListNode leftSorted = mergesort(head);\n        ListNode rightSorted = mergesort(mid);\n        return merge(leftSorted, rightSorted);\n    }\n\n    /** split the given list into two and return the pointer to the second half */\n    private static ListNode split(ListNode head) {\n        ListNode fast = head.next;\n        ListNode slow = head;\n        while (fast != null && fast.next != null) {\n            fast = fast.next.next;\n            slow = slow.next;\n        }\n\n        ListNode mid = slow.next;\n        slow.next = null;\n        return mid;\n    }\n\n    /** merge left list and right list */\n    private static ListNode merge(ListNode left, ListNode right) {\n        ListNode sentinel = new ListNode(0, null);\n        ListNode rear = sentinel;\n        while (left != null && right != null) {\n            if (left.val <= right.val) {\n                ListNode temp = left;\n                left = left.next;\n                temp.next = null;\n                rear.next = temp;\n            } else {\n                ListNode temp = right;\n                right = right.next;\n                temp.next = null;\n                rear.next = temp;\n            }\n            rear = rear.next;\n        }\n\n        if (left == null) {\n            while (right != null) {\n                ListNode temp = right;\n                right = right.next;\n                temp.next = null;\n                rear.next = temp;\n                rear = rear.next;\n            }\n        } else { // right == null\n            while (left != null) {\n                ListNode temp = left;\n                left = left.next;\n                temp.next = null;\n                rear.next = temp;\n                rear = rear.next;\n            }\n        }\n\n        return sentinel.next;\n    }\n}\n

时间复杂度 $O(NlogN)$ ，空间复杂度 $O(1)$ ，顺利 AC。

对 SLList 进行 quicksort 用 Java 太难实现了，遂放弃。（因为 Java 方法只能返回一个值，并且不能像 C/C++ 一样传递指针的指针来实现多返回值。）

SLList 的节点只有一个指针空间，故也不能实现 Heapsort。所以 mergesort 事坠吼的。

但是有一点小问题：为了避免 mergesort 的 worst case，在数组版本中首先对待排序数组进行 shuffle，链表好像不是很好进行 shuffle。第二个就是为了方便在 SLList 中进行节点插入删除，我使用了 currentPrev.next == current。但感觉这样很不优雅，不知道有没有什么修改方法。

Insertion sort 中我函数抽象的层次不对，应该把可复用的 swap() 抽象出来，而不是依赖于调用函数的 swapHelper()。

但是不太喜欢网课，主要是看书学，再配上做一些题目。会做一些 CS61b 的 hw 和 proj。然后我和 @TsuinoSora 看的都是 Spring 2018 学期。

很多朋友都会觉得 Graphics 只和游戏强相关，但其实完全不是这样……就工作来说，除了游戏以外还包括：

视频和动画三维特效，比如字节一直在招聘有图形学背景的人去抖音核心部门做视频特效
CAD/CAM/CAE，比如 Autodesk 这样的外企或者中望这样的国内企业，又或者上海有一些做 3D 打印的企业对图形学背景也有很强的需求
动画和影视，目前为止主要是国外（美国）有条件，比如皮克斯、迪士尼都有极强的图形学需求和实力，国内这方面还很菜，刚刚开始有一点（比如负责流浪地球的图形特效的那个公司）
SLAM 和三维重建，比如各种做文物/城市数字化、GIS、自动驾驶和导航的公司，这就属于比较散碎的需求了，但也不少

国内这些方向搞图形的企业，如果说和互联网/游戏比高薪那确实是比不过的，但也不算差，毕竟不是每个人都有互联网大厂 SP offer 的，其他条件那就得具体对比了。国外像 NVIDIA、Autodesk、迪士尼这些待遇应该是不输互联网的，不过难度也都很高。

如果想搞学术，现在除了经典图形之外 3D Vision 和 Vision for Graphics 也算是相当热门，因为门槛比纯 2D CV 要高不少所以处在竞争激烈但还没白热化的阶段。
