解题思路:
注意事项:
参考代码:
public class 盐水的故事 {
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner in = new Scanner(System.in);
int VUL = in.nextInt();
int D = in.nextInt();
int time = 0;
int sumVul = 0;
for (int i = 1; i <= VUL / 2; i++) {
if ((sumVul + i * D) < VUL) {
sumVul += i * D;
time = time + 1 + i;
} else if ((sumVul + i * D) == VUL) {
time = time + i;
break;
} else {
int yx = VUL - sumVul;
while (yx > 0) {
yx = yx - D;
time = time + 1;
}
break;
}
}
System.out.print(time);
}
}
