Problem DescriptionAcmer in HDU-ACM team are ambitious, especially sh, he can spend time in Internet bar doing problems overnight. so far girls want to meet and Orz him. but Orz him is not that easy. you must solve this problem first. the problem is:

Find the duplicate number. The first reaction is MAP (which they use for hash), which is easy to write (I am a pointer to the weak slag). However, some traps have been found during actual application, leading to several wa. the principle is very

The QSettings class is associated with related files (different platforms and different file types) to save some settings of the application. The following is a simple test of QSettings, for more information, see [cpp] # include # include #

[Cpp] // pair: For a group, two values (first, second) can be considered as a unit (pair), which is a template class. For map/multimap, pairs is used to manage pair elements of value/key. Any function needs to return two values, or pair # include #

Calculate the minimum number of characters to make the given string into a return text. The direct dp, dp [I] [j] represents the minimum number of characters in the string from I to j. 1. If a [I] = a [j], dp [I] [j] = dp [I + 1] [J-1], no new

In one of our POWERPC systems, an FPGA and NorFlash peripherals are mounted through the bus. Previously, we used to burn NorFlash through jtag, which was slow and difficult to operate. Now with PGA, tpu decides to put 4 K code in it for downloading

QuickSort is also a Sort Algorithm for input arrays containing n arrays. The worst run time is O (n ^ 2 ). Although the Run Time in the worst case is relatively poor, fast sorting is usually the best practical choice for sorting, because its average

Infinite Duration: 1 s memory: 32 M★Problem description: we generate two infinite numbers. The first number is a number that links all natural numbers. The second number is a number that connects the square of all natural numbers. Sum the two

How to bind a C/C ++ object to Lua? Generally, create a userdata, store the C/C ++ Object Pointer, add a meta table to userdata, and map the object methods in C/C ++ using the index meta method. There is another way to directly use lightuserdata to

The second Classic Mode for releasing messages is one-way data distribution. The server pushes updates to a group of clients. Let's take a look at an example of pushing weather changes, including the region code, temperature, and relative humidity.

When C ++ uses class functions, it is often used in multiple functions of different classes continuously to create class objects. To avoid this repetitive creation process, the following two methods are described to build a single object or a single
