Many of my friends will find that the capacity will decrease when they buy a mobile hard drive and a USB flash drive inserted into the computer. Originally, the 16 gb usb flash drive would be less than 16 GB, and the 1 TB mobile hard drive would be only 931 GB. In fact, it is found that most of the time the capacity is insufficient on the Windows platform, if it

When using asset or Res/raw in Android, you must go through asset manager. When using these two resource delivery methods, you must pay attention to the file size. After debugging, it is found that the uncompress_data_max value of the resource file in asset or Res/raw is 1048576 bytes, that is, the maximum size is not compressed 1 MB. Otherwise, the message of the obtained debug type will be displayed in logcat, 04-09 02:48:51. 220: Debug/asset (10734

Tag: loop. A ball is freely dropped from the height of MB. After each landing, the ball jumps back to half of the original height, then drops, and then rebounds. How many meters did it pass when it landed for 10th times? How high is the rebound for 10th times?Float H = 100; // initial height/// Rebound height//Float sum = 0; // The distance traveled// This is a loop that does not know how many times, so you should consider whether you need to use a wh

Method 2 can be used when n is very small, When N is large, you can use method 1 to read data from the hard disk one by one; /* Method 1 is suitable for a large amount of data * Search for the first m elements of the n Array and output them. * Use array n to create a m-large max heap based on the heap nature, and then output the heap content. * Time Complexity Analysis: heap creation time O (m) * Traverse numbers and compare time O (N-M) logm) in the heap) * Total time complexity O (m) + O (N-M)

Recently solved a problem-reducing memory usage. However, this method can only be used in WINXP and Win2k, without displaying that the main form is always running.ProgramBest. In the past, the program used 11 MB of memory. I used the dynamic window creation method to reduce the size by less than 100 kb. After applying this method, the memory usage was only 496 kb.
