Will Android’s switch to AAB installation package become a stumbling block for Hongmeng? won’t
For example, Hongmeng OS, which is entrusted with the important task of building a domestic mobile ecosystem and breaking the status quo of technology “stuck neck”, and Windows 11, which has just been released. Android applications compatible with these systems use APK format installation packages. Now that Google is pushing the new AAB format, is it intended to kick away these competitors who are using APK compatibility to rub against the Android ecosystem? Let’s just chat today. What is the AndroidAAB format Before talking about this issue, we need to have a little understanding of the AAB format. In fact, Google has been promoting the AAB format since 2018. Compared with APK, the biggest advantage of AAB lies in saving volume. We know that there are so many Android models, and if an Android App wants to be compatible with a large number of devices, it needs to build a lot of additional configuration files to adapt to different screen specifications, CPU models, RAM capacity, etc. In the traditional APK installation package, all configuration files will be packaged together, and the device installation APK will write these data into the mobile phone. But in reality, you don’t need all these…

Introduction: This article is compiled by the editor of Programming Notes# for you. It mainly introduces the knowledge related to the average value of the array after deleting some elements in “Practice every day, happy water question” 1619. I hope it will be helpful to you reference value. Article Table of Contents 🔴 Li button the original title ： 🟠Brief description of the topic： 🟡Problem solving ideas： 🟢C++ ;code ： 🔵result display ： 🔴Lee deduction original title： 1619. Array mean value after deleting some elements 🟠 ;Title Description ： Give you an integer array arr ， Please delete the smallest 5% of the numbers and the largest 5% of the numbers ， the average of the remaining numbers. A result within 10-5 of the standard answer is considered correct. Example 1 ： Enter ：arr = [1,2,2,2,2,2,2,2,2,2, 2,2,2,2,2,2,2,2,2,3] Output ：2.00000 Explanation ：after removing the largest and smallest elements in the array： xff0c;All elements are equal to 2，so the average is 2. Example 2 ： Enter ：arr = [6,2,7,5,1,2,0,3,10,2,5,0 ,5,5,0,8,7,6,8,0] Output ：4.00000 Example 3 ： Input ：arr & #61; [6,0,7,0,7,5,7,8,3,4,0,7,8,1,6,8,1,1,2,4,8,1,9, 5,4,3,8,5,10,8,6,6,1,0,6,10,8,2,3,4] Output ：4.77778Example 4& #xff1a; Enter ：arr=[9,7,8,7,7,8,4,4,6,8,8,7,6,8,8 ,9,2,6,0,0,1,10,8,6,3,3,5,1,10,9,0,7,10,0,10,4,1,10,6,9 ,3,6,0,0,2,7,0,6,7,2,9,7,7,3,0,1,6,1,10,3] output ： 5.27778 Example 5 ： Input ：arr = [4,8,4,10,0,7,1,3,7,8,8, 3,4,1,6,2,1,1,8,0,9,8,0,3,9,10,3,10,1,10,7,3,2,1,4,9, 10,7,6,4,0,8,5,1,2,1,6,2,5,0,7,10,9,10,3,7,10,5,8,5,7, 6,7,6,10,9,5,10,5,5,7,2,10,7,7,8,2,0,1,1]…
Appreciation and analysis of the original translation of “Su Hongqiao Jimeng” Poet Mingjing Pianpian
The dream mirror can still be remembered, but Hongqiao is suspicious. It’s because of the arrival of the magpie, it’s the period of the morning glory. The falling moon pierces through the curtains, and the bleak wind enters the night sadly. On the pillow with endless corners, life is suing the eyebrows. Comment 【Comment】：
