The Bruker-FOSS algorithmThe simple pattern matching algorithm is a kind of matching algorithm with backtracking.I. Algorithmic thinkingStarting from the POS character of the main string s, and comparing with the first character of the pattern string T, if the equality continues to compare subsequent characters, and if not, then the pos+1 characters from (back to) the main string s begin to be compared with the pattern string T. Until each character i

How to compile the Opus audio codec library for AndroidThe Opus audio codec library is the next generation of the Speex audio codec library. It has made great progress in terms of codec performance and quality. Opus compilation is very simple, but the official did not provide a detailed Android version Compilation Guide, find a lot of information, after many test

This series of content, based on two magnum opus: "Thinking in Java" (fourth edition) and "Effective Java" (second edition). This series is from these two masterpieces, but from another perspective, you will reap some different knowledge of the generic system content. This series includes the following eight:The first section: "The origin of generics", only understand the background and causes of generics, understand the generics to solve what problem

range of Android phones, manufacturers of the underlying source changes are different, resulting Mediacodec API in the actual use, will encounter many pits, there are many compatibility issues, so we can also consider the use of third-party codec library.Here, I simply recommend a few third-party audio codec libraries (can be ported to the Android platform), you can go directly to the official website or the project page to learn more about the details.(1)
