Before you develop this program, explain why the toast message prompt disappears after a certain amount of time is displayed. Because there is a toast queue in the Android system, a toast is taken out of the queue and displayed in turn. After the specified time is displayed, close it. Wouldn't it be possible to have the Toast info box show up all the time? This requirement is a bit of a imposition for toasts, because the toast itself does not provide

/** * Quick sort: Unstable, time complexity best O (nlogn) worst time O (n^2) * Quick Sort is an essential improvement on bubble sorting. Its basic idea is that after a scan, the length of the sequencing sequence can be significantly reduced. In a bubbling sort, a scan can only ensure that the number of maximum values is moved to the correct position, while the length of the sequence to be sorted may be red
The Qt Quick Controls were originally developed to support desktop platforms, and later joined the support of mobile platforms and embedded platforms. They are widely used because they provide a flexible style system that allows for the development of applications with platform-related or unrelated styles.
In embedded systems, hardware resources are limited, the system may be relatively inefficient. The QT Quick
Open the Win7 Quick Launch barMany netizens must remember that Windows systems prior to Windows 7 have a quick Start (launch) area.For example, IE browser, Windows Media Player program can be quickly launched inside.The Quick Launch toolbar uses the files in the following folder:%USERPROFILE%\Application Data\Microsoft\Internet Explorer\
When the internet is not only looking at the Web page, users of the browser requirements are increasingly high. It is imminent to break the traditional thinking and provide innovative functions.

Sircharlesantonyrichard dhoare is a British computer scientist and inventor of the famous QuickSort. On average, the number of tasks to be sorted must be compared by nlogn times, and it is generally faster than other nlogn algorithms. Therefore, it is a widely used algorithm. In an interview, Hall talked about the background of the algorithm.
The last article introduced the nature of sorting and the implementation of the fast sorting algorithm in Introduction to Algorithms. However, there is not

Quick sort because of the efficiency of sorting efficiency in several sorts of the same O (N*logn), so it is often adopted, coupled with the idea of fast ordering----divide and conquer method is also practical, so many software company's written interview, including such as Tencent, Microsoft and other well-known IT companies like to test this, There are large size of the procedures of the examination, such as soft test, postgraduate grind in also oft
The fast sort is a sort of division Exchange C.r.a.hoare in 1962. It adopts a strategy of divide and conquer, which is often referred to as the Partition method (Divide-and-conquermethod).
The basic idea of the method is:
1. First, take a number out of the series as the base number.
2. The partitioning process, which places the number larger than this to its right, is less than or equal to its number on the left.
3. Repeat the second step to the left and right intervals until the interval is onl
