解题思路:





注意事项:





参考代码:

import java.util.Scanner;

public class C1010 {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

while (scanner.hasNext()) {

int x = scanner.nextInt();

double y = function(x);

System.out.println((int)y);

}

scanner.close();

}

private static double function(double x) {

if(x <= 100000){

return x*0.1;

}else if(x > 100000 && x <= 200000){

return (x-100000)*0.075+100000*0.1;

}else if(x > 200000 && x <= 400000){

return (x-200000)*0.05+100000*0.075+100000*0.1;

}else if(x > 400000 && x <= 600000){

return (x-400000)*0.03+200000*0.05+100000*0.075+100000*0.1;

}else if(x > 600000 && x <= 1000000){

return (x-600000)*0.015+200000*0.03+200000*0.05+100000*0.075+100000*0.1;

}else if(x > 1000000){

return (x-1000000)*0.01+400000*0.015+200000*0.03+200000*0.05+100000*0.075+100000*0.1;

}else{

return 0;

}

}
