蓝桥杯基础练习VIP-Sine之舞 （Java代码）

解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String args[]){

Scanner sc = new Scanner(System.in);

int n = sc.nextInt();

//System.out.println(get(n));

for(int i=1;i<n;i++){

System.out.print("(");

}

for(int i=1;i<=n;i++){

System.out.print(get(i)+"+"+(n-i+1));

if(i!=n){

System.out.print(")");

}

}

}

//S3= ((A1+3)A2+2)A3+1

public static String get(int n){

String s = "";

for(int i=1;i<=n;i++){

if(i%2==0){

s += "-";

}else{

s += "+";

}

s += "sin(" + i;

}

for(int i=1;i<=n;i++){

s += ")";

}

s = s.substring(1,s.length());

return s;

}

//A1 = sin(1)

//A2 = sin(1-sin(2))

//A3 = sin(1-sin(2+sin(3)))

}
