Problem description: there are now n ordered arrays in M groups, such as {1, 2, 3, 4}, {2, 3, 6}, {1, 3, 5, 7 }, select the data smaller than K in these arrays and return this value. Idea: Compare the minimum data selected each time by referring to the process of merging two Arrays

By default, there are always three files open, standard input (keyboard input), standard output (output to screen), standard error (also output to screen), and their respective file descriptors are 0,1,2. So let's take a look at the differences between the following redirection methods:>/dev/null 2>1In fact, it should be equivalent to this: 1>/dev/null 2>/dev/nul

QML ranges from 1 to 2, and qml ranges from 1 to 2. As the project goes deeper, it needs to be transplanted to Android. The problem is that QML Android is compatible! Fortunately, the PC-side program is similar to the cell phone screen width ratio. Although the unit pixels and sizes are different, you can use proportio

What is a file descriptor. A file descriptor is a simple positive integer that identifies each file and socket that is opened by the process. The first three file descriptors (0,1,2) correspond to standard input (stdin), standard output (stdout), and standard error (STDERR) respectively. difference between "2>1 > File" and "> File 2>

The so-called calculation of the exact age is: birthday is not a day to grow one year old! Everyone commonly used, the number of years counted as age
