利用安卓现有漏洞直接像安卓10一样直接使用Android/data目录或者像安卓11一样授权Android/data目录,并且无需shizuku,只是简单写了一个授权和查看文件列表的实例,剩下直接参照别人开源的就可以,都差不多。

Data Structures & Algorithms Using JavaScript by Hemant Jain English | 17 May 2017 | ASIN: B072J44X62 | 614 Pages | AZW3 | 4.22 MB This book is about the usage of data structures and algorithms in computer programming. Designing an efficient algorithm to solve a computer science problem is a skill of Computer programmer. This is the skill which tech companies like Google, Amazon, Microsoft, Adobe and many others are looking for in an interview. This book assumes that you are a JavaScript language developer. You are not an expert in JavaScript language, but you are well familiar with concepts of references, functions, arrays and recursion. In the start of this book, we will be revising the JavaScript language fundamentals that will be used throughout this book. We will be looking into some of the problems in arrays and recursion too. Then in the coming chapter, we will be looking into complexity analysis. Then will look into the various data structures and their algorithms. We will be looking into a linked list, stack, queue, trees, heap, hash table and graphs. We will be looking into sorting, searching techniques. Then we will be looking into algorithm analysis, we will be looking into brute force algorithms, greedy algorithms, divide and conquer algorithms, dynamic programming, reduction, and backtracking. In the end, we will be looking into the system design that will give a systematic approach for solving the design problems in an Interview.
