这是跟着代码随想录的顺序学习算法的第三十二天。 以下是学习时自己的一些理解与笔记，如有错误欢迎指正与讨论。 332. 重新安排行程 参考相关链接： 332. 重新安排行程 代码随想录 笔记 在自己做本题的时候，写出来的解法超时了，原因是我先找到了所有路径存入一个数组，再将其进行
labuladong讲解 46. 全排列（中等） 题目： 给定一个不含重复数字的数组 nums ，返回其 所有可能的全排列 。你可以 按任意顺序 返回答案。 示例 1： 输入：nums = [1,2,3]输出：[[1,2,3],[1,3,2],[2,1,3],[2,3,1],[3,1,2],[3,2,1]] 思路： 使用回溯算法框架，遍历所有可能性，用used记录已经取走的
事件背景： 同事向我咨询了从jvm监控中看到的现象，大致描述就是：young gc 频繁，但是没有full gc，且堆内存一直保持在近100%的状态，线程变化稳定，CPU的使用率有波动，主要和young gc有关，具体情况见下图1。然后我们就去运维平台，通过jmap平台查看堆内存的使用情况，前面的数据看起来正常，可是在看c

第一题：力扣46题 解题思路： 排序问题作为一个典型的回溯问题，其实和组合问题、回文字符串问题都有着密切的联系，只不过排序问题是有序的，这里在代码中给有详细注释。 代码如下： class Solution { List<List<Integer>> res = new ArrayList<>(); LinkedList<Integer> path =
A bucket is typically a watertight, vertical cylinder or truncated cone or square, with an open top and a flat bottom, attached to a semicircular carrying handle called the bail. 原来bail是桶的把手啊，怪不得还有“(板球)三柱门上的横木”的意思。可能当初某人指着“

思路 难点在于可能包含重复元素，因此对于同层的元素（同一位置），不能出现同样的数字，否则就会重复，而不同层可以出现重复数字。 func subsetsWithDup(nums []int) [][]int { res := [][]int{} cur := []int{} used := make([]bool, len(nums)) var backtracking f

如果我们粗俗地把每个晶体管看作边长为10nm的正方形，那么100亿个的面积是： 100 * 108 * 10 * 10-9 * 10 * 10-9 = 10-6 平米 = 1平方毫米 铁壳里面是die，不像1平方毫米的样子。 Orin is a 17 billion transistor chip, almost double the transistor count of Xavier and contin
