## Implementation with C + +: dance of Sine

Problem description
Recently, FJ has set up a mathematical analysis course for his cows. FJ knows that if he wants to learn this course well, he must have a good basic skill of trigonometric function. So he is going to play a game of "dance of Sine" with the cows to improve their computing power.
We might as well set
An=sin(1–sin( ...

## [TOJ 4705] maximum prime number

Description
Given a number n, ask whether it is possible to take consecutive bits from it in the order from left to right and combine them into a prime number (a number greater than 1 and only divisible by 1 and itself is called a prime number). If there are multiple possibilities, take the largest one of all possible numbers.
For example, in 1 ...

## Simple and clear interpolation audio resampling algorithm example (with complete C code)

In recent period of time, we have wandered back and forth between image algorithm and audio algorithm.
There are often some requirements for audio sampling and transcoding.
Existing well-known open source libraries, such as webrtc, Sox, etc,
Code reading is really disturbing.
And audio resampling is actually interpolation algorithm.
It is not m ...

## Data structure: recursive implementation and hierarchical implementation of tree traversal

Tree structure is an important nonlinear data structure. Tree is a finite set of n (n > = 0) nodes. In any non empty tree, there are and only
When n > 1, the remaining nodes can be divided into m (M > 0) disjoint finite sets T1,T2,...,Tm, each of which
The collection itself is a tree, and is called the root subtree. Therefore, the data ...
