Problem Description
Welcome to ‘Samuel Design Contest’.Samuel greets you a happy 牛 Year. At new year and always,may peace and love fill your heart,beauty fill your world,joy and contentment fill your life and may you make great progress during the coming year both in your ACM and your study. The following problems are intended for you,especially for those rookies(usually known as “vegetable bird”in Chinglish).As it always does,the first problem is the easiest,I believe that you can work it out in a few minutes. The problem goes like this: Samuel is engaged at this new year's season and has a lot of things to do. For instance,he needs to buy new clothes,to prepare some food,to decorate the house and the like. Here is the schedule.
Based on the schedule,you need to answer what will Samuel do in N days before the New Year(2009.1.26 i the Spring Festival).
 
Input
The input include 2 parts: t(an integer,presents the t test cases),n(an integer,means n days before the New Year).
 
Output
Just output what Samuel will do according to the schedule,like this”Samuel will *******.”.
 
Sample Input
3 13 3 2
 

Sample Output
Samuel will take test. Samuel will stay at home. Samuel will decorate.


AC代码:
#include<iostream>
#include<algorithm>
#include<cstring>
#include<cstdio>
int main()
{
    int t;
    int n;
    scanf("%d",&t);
    while(t--)
    {
        scanf("%d",&n);
         printf("Samuel will ");
        if(n==13)       printf("take test");
        else if(n==12)  printf("go home");
        else if(n==11)  printf("stay at home");
        else if(n==10)  printf("buy clothes");
        else if(n==9)   printf("buy food");
        else if(n==8)   printf("stay at home");
        else if(n==7)   printf("visit teachers");
        else if(n==6)   printf("go to KTV");
        else if(n==5)   printf("meet friends");
        else if(n==4)   printf("go to movies");
        else if(n==3)   printf("stay at home");
        else if(n==2)   printf("decorate");
        else if(n==1)   printf("decorate");
        else if(n==0)   printf("go out");
        else if(n==-1)  printf("be in the park");
        else if(n==-2)  printf("stay at home");
        else if(n==-3)  printf("visit relative");
        else if(n==-4)  printf("visit relative");
        else if(n==-5)  printf("stay at home");
        else if(n==-6)  printf("prepare dinner");
       printf(".\n");
    }
    return 0;
}
内容概要:该研究通过在黑龙江省某示范村进行24小时实地测试,比较了燃煤炉具与自动/手动进料生物质炉具的污染物排放特征。结果显示,生物质炉具相比燃煤炉具显著降低了PM2.5、CO和SO2的排放(自动进料分别降低41.2%、54.3%、40.0%;手动进料降低35.3%、22.1%、20.0%),但NOx排放未降低甚至有所增加。研究还发现,经济性和便利性是影响生物质炉具推广的重要因素。该研究不仅提供了实际排放数据支持,还通过Python代码详细复现了排放特征比较、减排效果计算和结果可视化,进一步探讨了燃料性质、动态排放特征、碳平衡计算以及政策建议。 适合人群:从事环境科学研究的学者、政府环保部门工作人员、能源政策制定者、关注农村能源转型的社会人士。 使用场景及目标:①评估生物质炉具在农村地区的推广潜力;②为政策制定者提供科学依据,优化补贴政策;③帮助研究人员深入了解生物质炉具的排放特征和技术改进方向;④为企业研发更高效的生物质炉具提供参考。 其他说明:该研究通过大量数据分析和模拟,揭示了生物质炉具在实际应用中的优点和挑战,特别是NOx排放增加的问题。研究还提出了多项具体的技术改进方向和政策建议,如优化进料方式、提高热效率、建设本地颗粒厂等,为生物质炉具的广泛推广提供了可行路径。此外,研究还开发了一个智能政策建议生成系统,可以根据不同地区的特征定制化生成政策建议,为农村能源转型提供了有力支持。
