蓝桥杯基础练习VIP-Sine之舞 （C语言代码） 还是递归法不伤脑筋

解题思路:

注意事项:

参考代码:

#include<stdio.h>

void An(int n,int i)                                    //输出An的函数

{

    if(n==i)printf("sin(%d)",n);

    else

    {

        if(i%2==1)printf("sin(%d-",i);

        else printf("sin(%d+",i);

        An(n,i+1);

        printf(")");

    }

}

void Sn(int n,int i)                                    //输出Sn的函数

{

    if(n==1)

    {

        int k=1;

        An(n,k);

        printf("+%d",i);

    }

    else

    {

        int k=1;

        printf("(");

        Sn(n-1,i+1);

        printf(")");

        An(n,k);

        printf("+%d",i);

    }

}

int main()

{

    int n,i=1;

    scanf("%d",&n);

    Sn(n,i);

    printf("\n");

}
