思路:
税+税后所得A=税前工资S。
因为工资是整百的数,每次减100来判断。好理解但是超时。
import java.util.Scanner;
//只有90分,超时了
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int T = sc.nextInt();
if(T < 3500) {
System.out.println(T);
}
double x = 0;//税钱
int S = 200000;//假设一个月最多挣20万
int A = S - 3500;
while(true)
{
if(A <= 1500)
x = A * 0.03;
else if(A <= 4500)
x = 45 + (A - 1500) * 0.1;
else if(A <= 9000)
x = 45 + 300 + (A - 4500) * 0.2;
else if(A <= 35000)
x = 45 + 300 + 900 + (A - 9000) * 0.25;
else if(A <= 55000)
x = 45 + 300 + 900 + 6500 + (A - 35000) * 0.3;
else if(A <= 80000)
x = 45 + 300 + 900 + 6500 + 6000 + (A - 55000) * 0.35;
else
x = 45 + 300 + 900 + 6500 + 6000 + 8750 + (A - 80000) * 0.45;
if(S == x + T)
break;
S = S - 100;
A = S - 3500;
}
System.out.println(S);
}
}
