If you only want to modify the screen brightness of the current app, there's another way: Set the properties of the Window for the Activity. The corresponding Java code is as follows: Windowmanager.layoutparams LP = Window.getattributes (); lp.screenbrightness = brightness; Window.setattributes (LP);If you want to implement the above Java code through JNI in Qt, y

the lock is idle but cannot obtain it, it will be withdrawn before retry. To prevent conflicting concurrent threads from entering the lock acquisition step, that is, all threads attempt to obtain the lock at the same time point, the thread should be randomly withdrawn for a period of time. Every time a thread tries to obtain a lock but fails, it doubles the return time until a fixed maximum value of maxdelay is reached.

And if a number is exactly equal to the sum of factors other than itself, this number is called the end number. For example 6=1+2+3 (6 of the factor is the one-to-be).Now you are going to write a program that reads two positive integers n and M (1Tip: You can write a function to determine w
