. The speed pointer is used.2. Starting from the position where the fast and slow pointers meet, the slow pointer and the other pointer starting from the starting position take one step each time until they meet, that is, where the duplicate node occurs.Implementation Code: public class Solution { public int FindDuplicate(int[] nums) { // define slow and fast , fast each time move 2 times var slow = 0; var fast = 0; while(true) { slow = nums[slow]; fast = nums

In the Mac OS X operating system of apple, there are many ways to hide the display of files. The simplest method is to enter commands on the Mac terminal. The command for displaying/hiding a Mac hidden file is as follows (note the spaces and make them case sensitive ):Command for displaying Mac hidden files: Defaults write com. Apple.

unacceptable for a long string, perhaps we should be "on demand", So there's the iterator approach. 4.2 iterators Boost::algorithm::split_iterator can be used to split strings, and it also needs to be paired with some finder (such as Token_finder) and an assertion (or a judgment). Of course we can also DIY a finder. The following is a simple routine: #include #include using namespace Std; #include int

1. Find a local file (Plist,.m,.h can), copy the suffix name to txt directly, and then edit the content is OK. is not very witty! I believe most people already know.2. Under the Finder press +SHIFT+G, you can open the "Go To Folder" dialog box, you can enter the path to quickly access the Finder directory location, to locate file operations, which is undoubtedly the fastest way. In addition, you do not have

The goal of the POLYFORMS project is to eliminate duplicate code for binding data access objects and the underlying persistence APIs. The approach to this framework is to automate the implementation of service methods on repository interfaces defined by developers. The method defined in the interface is connected to the database operation by default through a naming convention. For example, the project Wiki discusses how to implement a storage for the user entity object. First, the stored APIs m
